qualcommbe: ipq95xx: Add initial support for new target

Browse Source 
Add initial support for new target with the initial patch for ethernet
support using pending upstream patches for PCS UNIPHY, PPE and EDMA.

Only initramfs currently working as support for new SPI/NAND
implementation, USB, CPUFreq and other devices is still unfinished and
needs to be evaluated.

Subject: [PATCH 1/2] clk: qcom: clk-rcg: introduce support for multiple conf
for same freq
Some RCG frequency can be reached by multiple configuration.
We currently declare multiple configuration for the same frequency but
that is not supported and always the first configuration will be taken.
These multiple configuration are needed as based on the current parent
configuration, it may be needed to use a different configuration to
reach the same frequency.
To handle this introduce 3 new macro, C, FM and FMS:
- C is used to declare a freq_conf where src, pre_div, m and n are
provided.
- FM is used to declare a freq_multi_tbl with the frequency and an
array of confs to insert all the config for the provided frequency.
- FMS is used to declare a freq_multi_tbl with the frequency and an
array of a single conf with the provided src, pre_div, m and n.
Struct clk_rcg2 is changed to add a union type to reference a simple
freq_tbl or a complex freq_multi_tbl.

Subject: [PATCH 2/2] clk: qcom: clk-rcg2: add support for rcg2 freq multi ops
Some RCG frequency can be reached by multiple configuration.
Add clk_rcg2_fm_ops ops to support these special RCG configurations.
These alternative ops will select the frequency using a CEIL policy.
When the correct frequency is found, the correct config is selected by
calculating the final rate (by checking the defined parent and values
in the config that is being checked) and deciding based on the one that
is less different than the requested one.
These check are skipped if there is just one config for the requested
freq.
qcom_find_freq_multi is added to search the freq with the new struct
freq_multi_tbl.
__clk_rcg2_select_conf is used to select the correct conf by simulating
the final clock.
If a conf can't be found due to parent not reachable, a WARN is printed
and -EINVAL is returned.

Subject: [PATCH] clk: qcom: branch: Add clk_branch2_prepare_ops
Add the clk_branch2_prepare_ops for supporting clock controller
where the hardware register is accessed by MDIO bus, and the
spin lock can't be used because of sleep during the MDIO
operation.
The clock is enabled by the .prepare instead of .enable when
the clk_branch2_prepare_ops is used.

Subject: [PATCH] net: phy: introduce core support for phy-mode = "10g-qxgmii"
10G-QXGMII is a MAC-to-PHY interface defined by the USXGMII multiport
specification. It uses the same signaling as USXGMII, but it multiplexes
4 ports over the link, resulting in a maximum speed of 2.5G per port.
Some in-tree SoCs like the NXP LS1028A use "usxgmii" when they mean
either the single-port USXGMII or the quad-port 10G-QXGMII variant, and
they could get away just fine with that thus far. But there is a need to
distinguish between the 2 as far as SerDes drivers are concerned.

Subject: [PATCH] clk: Provide devm_clk_bulk_get_all_enabled() helper
Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk
clocks") added devm_clk_bulk_get_all_enable() function, but missed to
return the number of clocks stored in the clk_bulk_data table referenced
by the clks argument. Without knowing the number, it's not possible to
iterate these clocks when needed, hence the argument is useless and
could have been simply removed.
Introduce devm_clk_bulk_get_all_enabled() variant, which is consistent
with devm_clk_bulk_get_all() in terms of the returned value:
> 0 if one or more clocks have been stored
= 0 if there are no clocks
< 0 if an error occurred
Moreover, the naming is consistent with devm_clk_get_enabled(), i.e. use
the past form of 'enable'.
To reduce code duplication and improve patch readability, make
devm_clk_bulk_get_all_enable() use the new helper, as suggested by
Stephen Boyd.

Subject: [PATCH] interconnect: icc-clk: Specify master/slave ids
Presently, icc-clk driver autogenerates the master and slave ids.
However, devices with multiple nodes on the interconnect could
have other constraints and may not match with the auto generated
node ids.
Hence, modify the driver to use the master/slave ids provided by
the caller instead of auto generating.
Also, update clk-cbf-8996 accordingly.

Subject: [PATCH] clk: qcom: common: Add interconnect clocks support
Unlike MSM platforms that manage NoC related clocks and scaling
from RPM, IPQ SoCs dont involve RPM in managing NoC related
clocks and there is no NoC scaling.
However, there is a requirement to enable some NoC interface
clocks for accessing the peripheral controllers present on
these NoCs. Though exposing these as normal clocks would work,
having a minimalistic interconnect driver to handle these clocks
would make it consistent with other Qualcomm platforms resulting
in common code paths. This is similar to msm8996-cbf's usage of
icc-clk framework.

Subject: [PATCH] arm64: dts: qcom: ipq9574: Add icc provider ability to gcc
IPQ SoCs dont involve RPM in managing NoC related clocks and
there is no NoC scaling. Linux itself handles these clocks.
However, these should not be exposed as just clocks and align
with other Qualcomm SoCs that handle these clocks from a
interconnect provider.
Hence include icc provider capability to the gcc node so that
peripherals can use the interconnect facility to enable these
clocks.

+description:
+ Qualcomm QCA8084 is a four-port Ethernet transceiver, the
+ Ethernet port supports link speed 10/100/1000/2500 Mbps.
+ There are two PCSes (PCS0 and PCS1) integrated in the PHY
+ package, PCS1 includes XPCS and PCS to support the interface
+ mode 10G-QXGMII and SGMII, PCS0 includes a PCS to support the
+ interface mode SGMII only. There is also a clock controller
+ integrated in the PHY package. This four-port Ethernet
+ transceiver can also be integrated to the switch chip named
+ as QCA8386. The PHY package mode needs to be configured as the
+ correct value to apply the interface mode of two PCSes as
+ mentioned below.
+
+ QCA8084 expects an input reference clock 50 MHZ as the clock
+ source of the integrated clock controller, the integrated
+ clock controller supplies the clocks and resets to the
+ integrated PHY, PCS and PHY package.

Subject: [PATCH 02/50] net: phy: qca808x: Add QCA8084 ethernet phy support
Add QCA8084 Quad-PHY support, which is a four-port PHY with
maximum link capability of 2.5 Gbps. The features of each port
are almost same as QCA8081. The slave seed and fast retrain
configs are not needed for QCA8084. It includes two PCSes.
PCS0 of QCA8084 supports the interface modes:
PHY_INTERFACE_MODE_2500BASEX and PHY_INTERFACE_MODE_SGMII.
PCS1 of QCA8084 supports the interface modes:
PHY_INTERFACE_MODE_10G_QXGMII, PHY_INTERFACE_MODE_2500BASEX and
PHY_INTERFACE_MODE_SGMII.
The additional CDT configurations needed for QCA8084 compared
with QCA8081.

From fd5ec7c0a9f7167baf377a4bbae72eda391df996 Mon Sep 17 00:00:00 2001

Date: Wed, 8 Nov 2023 16:18:02 +0800
Subject: [PATCH 03/50] net: phy: qca808x: Add config_init function for QCA8084
1. The ADC of QCA8084 PHY must be configured as edge inverted
and falling whenever it is initialized or reset. In addition,
the default MSE (Mean square error) threshold value is adjusted,
which comes into play during link partner detection to detect
the valid link signal.
2. Add the possible interface modes.
When QCA8084 works on the interface mode SGMII or 2500BASE-X, the
interface mode can be switched according to the PHY link speed.
When QCA8084 works on the 10G-QXGMII mode, which will be the only
possible interface mode.

for QCA8084
QCA8084 integrates clock controller and security control modules
besides of the PHY and PCS. The 32bit registers in these modules
are accessed using special MDIO sequences to read or write these
registers.
The MDIO address of PHY and PCS are configured by writing to the
security control register. The package mode for QCA8084 is also
configured in a similar manner.

2500BASEX mode is used when PCS connects with QCA8386 switch in a fixed
2500M link. It is also used when PCS connectes with QCA8081 PHY which
works at 2500M link speed. In addition, it can be also used when PCS
connects with a 2.5G SFP module.

Subject: [PATCH 18/50] net: ethernet: qualcomm: Add PPE driver for IPQ9574 SoC
The PPE (Packet Process Engine) hardware block is available
on Qualcomm IPQ SoC that support PPE architecture, such as
IPQ9574.
The PPE in IPQ9574 includes six integrated ethernet MAC
(for 6 PPE ports), buffer management, queue management and
scheduler functions. The MACs can connect with the external
PHY or switch devices using the UNIPHY PCS block available
in the SoC.
The PPE also includes various packet processing offload
capabilities such as L3 routing and L2 bridging, VLAN and
tunnel processing offload. It also includes Ethernet DMA (EDMA)
function for transferring packets between ARM cores and PPE
ethernet ports.
This patch adds the base source files and Makefiles for the PPE
driver such as platform driver registration, clock initialization,
and PPE reset routines.

Subject: [PATCH 19/50] net: ethernet: qualcomm: Add PPE buffer manager
configuration
The BM (Buffer Management) config controls the pause frame generated
on the PPE port. There are maximum 15 BM ports and 4 groups supported,
all BM ports are assigned to group 0 by default. The number of hardware
buffers configured for the port influence the threshold of the flow
control for that port.

Subject: [PATCH 20/50] net: ethernet: qualcomm: Add PPE queue management
config
QM (queue management) config decides the length of PPE port queues
and the threshold to drop packet.
There are two types of PPE queue, unicast queue (0-255) and multicast
queue (256-299) are configured with different length, which are used
to forward the different types of traffic.

Configure unicast and multicast hardware queues to forward
the traffic between PPE ports.
Each PPE port is assigned with the specific queue resource,
and the egress queue ID is decided by the priority and the
RSS hash value of packet.

Subject: [PATCH 23/50] net: ethernet: qualcomm: Add PPE service code config
Configure service code for marking the traffic passed through
PPE. Service code is generated according the features of packet
when the packet is processed by PPE.
The bypass features of service code 1 is configured by default,
which used by CPU port when the packet is transmitted from host
to the CPU port of PPE.

From 244012f3f879d4709be68e7ddabc064268bbd69e Mon Sep 17 00:00:00 2001
From: Lei Wei <quic_leiwei@quicinc.com>
Date: Thu, 28 Dec 2023 00:38:08 +0800
Subject: [PATCH 27/50] net: ethernet: qualcomm: Add PPE L2 bridge
initialization
The per-port L2 bridge settings are initialized as follows:
For PPE CPU port, the PPE bridge Tx is enabled and FDB learn is
disabled. For PPE physical port, the PPE bridge Tx is disabled
and FDB learn is enabled by default and the L2 forward action
is initialized as forward to CPU port.

Subject: [PATCH 33/50] net: ethernet: qualcomm: Add PPE port MAC MIB
statistics functions
Add PPE port MAC MIB statistics functions which are used by netdev
ops and ethtool. For GMAC, a polling task is scheduled to read the
MIB counters periodically to avoid 32bit register counter overflow.

Subject: [PATCH 1/5] dt-bindings: clock: qcom: Add CMN PLL clock controller
for IPQ SoC
The CMN PLL controller provides clocks to networking hardware blocks
and to GCC on Qualcomm IPQ9574 SoC. It receives input clock from the
on-chip Wi-Fi, and produces output clocks at fixed rates. These output
rates are predetermined, and are unrelated to the input clock rate.
The primary purpose of CMN PLL is to supply clocks to the networking
hardware such as PPE (packet process engine), PCS and the externally
connected switch or PHY device. The CMN PLL block also outputs fixed
rate clocks to GCC, such as 24 MHZ as XO clock and 32 KHZ as sleep
clock supplied to GCC.

Subject: [PATCH 2/5] clk: qcom: Add CMN PLL clock controller driver for IPQ
SoC
The CMN PLL clock controller supplies clocks to the hardware
blocks that together make up the Ethernet function on Qualcomm
IPQ SoCs and to GCC. The driver is initially supported for
IPQ9574 SoC.
The CMN PLL clock controller expects a reference input clock
from the on-board Wi-Fi block acting as clock source. The input
reference clock needs to be configured to one of the supported
clock rates.
The controller supplies a number of fixed-rate output clocks.
For the IPQ9574, there is one output clock of 353 MHZ to PPE
(Packet Process Engine) hardware block, three 50 MHZ output
clocks and an additional 25 MHZ output clock supplied to the
connected Ethernet devices. The PLL also supplies a 24 MHZ
clock as XO and a 32 KHZ sleep clock to GCC, and one 31.25
MHZ clock to PCS.

Subject: [PATCH 4/5] arm64: dts: qcom: Add CMN PLL node for IPQ9574 SoC
The CMN PLL clock controller allows selection of an input clock rate
from a defined set of input clock rates. It in-turn supplies fixed
rate output clocks to the hardware blocks that provide the ethernet
functions such as PPE (Packet Process Engine) and connected switch or
PHY, and to GCC.
The reference clock of CMN PLL is routed from XO to the CMN PLL through
the internal WiFi block.
.XO (48 MHZ or 96 MHZ)-->WiFi (multiplier/divider)-->48 MHZ to CMN PLL.
The reference input clock from WiFi to CMN PLL is fully controlled by
the bootstrap pins which select the XO frequency (48 MHZ or 96 MHZ).
Based on this frequency, the divider in the internal Wi-Fi block is
automatically configured by hardware (1 for 48 MHZ, 2 for 96 MHZ), to
ensure output clock to CMN PLL is 48 MHZ.

Subject: [PATCH 1/7] clk: qcom: clk-alpha-pll: Add NSS HUAYRA ALPHA PLL
support for ipq9574
Add support for NSS Huayra alpha pll found on ipq9574 SoCs.
Programming sequence is the same as that of Huayra type Alpha PLL,
so we can re-use the same.

Subject: [PATCH 13/17] arm64: dts: qcom: ipq9574: Add PCS UNIPHY device tree
support
The UNIPHY block in the IPQ SoC enables PCS/XPCS functions and helps in
interfacing the Ethernet MAC to external PHYs.
There are three PCS UNIPHY instances available in the IPQ9574 SoC. The
first UNIPHY has four PCS channels which can connect to QCA8075 Quad
PHYs in QSGMII mode or QCA8085 PHYs with 10G-QXGMII mode. The second
and third UNIPHYs each has one PCS channel which can connect with single
10G capable PHY such as Aquantia 113c PHY in USXGMII mode.

Subject: [PATCH 17/17] arm64: dts: qcom: Add IPQ9574 RDP433 port node
There are 6 PPE MAC ports available on RDP433. The port1-port4 are
connected with QCA8075 QUAD PHYs through UNIPHY0 PCS channel0-channel3.
The port5 is connected with Aquantia PHY through UNIPHY1 PCS channel0
and the port6 is connected with Aquantia PHY through UNIPHY2 PCS
channel0.

Subject: [PATCH] dt-bindings: clock: Add clock ID for IPQ PCS UNIPHY
IPQ9574 expose 3 PCS UNIPHY that expose all the same clock ID for RX and
TX clock. This is needed to correctly parent the EDMA ports and scale
to the correct frequency to permit correct function of attached PHY.

Subject: [PATCH] net: ethernet: qualcomm: Add support for label property for
EDMA port
Add support for label property for EDMA port. This is useful to define
custom name in DTS for specific ethernet port instead of assigning a
dynamic name at runtime.
This also improve the log output by using modern APIs.
