Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.

Subject: [PATCH 068/182] spi: qup: Convert ot let spi core handle checking
|
|
transfer speed
|
|
|
|
Set master->max_speed_hz then spi core will handle checking transfer speed.
|
|
So we can remove the same checking in this driver.
|
|
|
|
Also remove checking spi->chip_select in spi_qup_setup(), the checking is done
|
|
by spi core.
