Subject: [PATCH 2/8] net: stmmac: dwmac-stm32: refactor clock config
Currently, clock configuration is spread throughout the driver and
partially duplicated for the STM32MP1 and STM32 MCU variants. This makes
it difficult to keep track of which clocks need to be enabled or disabled
in various scenarios.
This patch adds symmetric stm32_dwmac_clk_enable/disable() functions
that handle all clock configuration, including quirks required while
suspending or resuming. syscfg_clk and clk_eth_ck are not present on
STM32 MCUs, but it is fine to try to configure them anyway since NULL
clocks are ignored.

Subject: [PATCH 3/8] net: stmmac: dwmac-stm32: Separate out external clock
rate validation
Pull the external clock frequency validation into a separate function,
to avoid conflating it with external clock DT property decoding and
clock mux register configuration. This should make the code easier to
read and understand.
This does change the code behavior slightly. The clock mux PMCR register
setting now depends solely on the DT properties which configure the clock
mux between external clock and internal RCC generated clock. The mux PMCR
register settings no longer depend on the supplied clock frequency, that
supplied clock frequency is now only validated, and if the clock frequency
is invalid for a mode, it is rejected.
Previously, the code would switch the PMCR register clock mux to internal
RCC generated clock if external clock couldn't provide suitable frequency,
without checking whether the RCC generated clock frequency is correct. Such
behavior is risky at best, user should have configured their clock correctly
in the first place, so this behavior is removed here.

Subject: [PATCH 4/8] net: stmmac: dwmac-stm32: Separate out external clock
selector
Pull the external clock selector into a separate function, to avoid
conflating it with external clock rate validation and clock mux
register configuration. This should make the code easier to read and
understand.
The dwmac->enable_eth_ck variable in the end indicates whether the MAC
clock are supplied by external oscillator (true) or internal RCC clock
IP (false). The dwmac->enable_eth_ck value is set based on multiple DT
properties, some of them deprecated, some of them specific to bus mode.
The following DT properties and variables are taken into account. In
each case, if the property is present or true, MAC clock is supplied
by external oscillator.
- "st,ext-phyclk", assigned to variable dwmac->ext_phyclk
- Used in any mode (MII/RMII/GMII/RGMII)
- The only non-deprecated DT property of the three
- "st,eth-clk-sel", assigned to variable dwmac->eth_clk_sel_reg
- Valid only in GMII/RGMII mode
- Deprecated property, backward compatibility only
- "st,eth-ref-clk-sel", assigned to variable dwmac->eth_ref_clk_sel_reg
- Valid only in RMII mode
- Deprecated property, backward compatibility only
The stm32mp1_select_ethck_external() function handles the aforementioned
DT properties and sets dwmac->enable_eth_ck accordingly.
The stm32mp1_set_mode() is adjusted to call stm32mp1_select_ethck_external()
first and then only use dwmac->enable_eth_ck to determine hardware clock mux
settings.
No functional change intended.

Subject: [PATCH 6/8] net: stmmac: dwmac-stm32: Clean up the debug prints
Use dev_err()/dev_dbg() and phy_modes() to print PHY mode instead of
pr_debug() and hand-written PHY mode decoding. This way, each debug
print has associated device with it and duplicated mode decoding is
removed.

Subject: [PATCH 5/5] ARM: dts: stm32: add ethernet1 for STM32MP135F-DK board
Ethernet1: RMII with crystal
Ethernet2: RMII with no cristal, need "phy-supply" property to work,
today this property was managed by Ethernet glue, but should be present
and managed in PHY node. So I will push second Ethernet in next step.
PHYs used are SMSC (LAN8742A)

Subject: [PATCH] mmc: mmci: stm32: add SDIO in-band interrupt mode
Add the support of SDIO in-band interrupt mode for STM32 and Ux500
variants.
It allows the SD I/O card to interrupt the host on SDMMC_D1 data line.
It is not enabled by default on Ux500 variant as this is unstable and
Ux500 users should use out-of-band IRQs.

Subject: [PATCH] rtc: stm32: add pinctrl and pinmux interfaces
STM32 RTC is capable to handle 3 specific pins of the soc.
"out1, out2 and out2_rmp". To handle this, we use pinctrl framework.
There is a single pin per group.

From 229476a4de2e237ebadddca8a82d20afa9298f71 Mon Sep 17 00:00:00 2001

Subject: [PATCH] rtc: stm32: add Low Speed Clock Output (LSCO) support
RTC is able to output on a pin the "LSE" internal clock.
STM32 RTC is now registered as a clock provider.
It provides rtc_lsco clock, that means RTC_LSCO is output on either
RTC_OUT1 or RTC_OUT2_RMP, depending on pinmux DT property.
The clock is marked as CLK_IGNORE_UNUSED and CLK_IS_CRITICAL because
RTC_LSCO can be early required by devices needed it to init.
Add LSCO in pinmux functions.
Add "stm32_rtc_clean_outs" to disable LSCO. As RTC is part of "backup"
power domain, it is not reset during shutdown or reboot. So force LSCO
disable at probe.
