Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

mmc: tmio: Check INFO1 for completion during DMA transfer

2024-04-15T06:19:12+00:00

In case a CRC error occurs during DMA transfer, the transfer completion
flag is not set in TMIO_SD_DMA_INFO1 and the transfer would eventually
time out. The timeout could be very long in case the transfer consists
of a large amount of blocks, the base timeout is 10 seconds and every
block adds 100 us more.

In case a CRC error does occur, a completion flag is set in a different
register, TMIO_SD_INFO1. Use this other completion flag to detect DMA
transfer ended and stop waiting for TMIO_SD_DMA_INFO1 completion flag.
This reduces the lengthy timeout in case of an error. The unconditional
check of TMIO_SD_DMA_INFO2 register for DMA related errors must not be
skipped in any case to actually recognize the DMA error and report it.

mmc: tmio: Disable 1/1024 clock divider on Renesas R-Car platforms

2023-10-27T09:21:28+00:00

The R-Car Gen3 SD_CLK_CTRL register does not use BIT(16) to implement
divider 1/1024, instead BIT(16) is reserved bit and divider 1/1024 is
not supported. The divider 1/1024 is specific to Socionext variant of
the IP, as is indicated by Linux commit:

0196c8db8363 ("mmc: tmio: move tmio_mmc_set_clock() to platform hook")
"
Socionext (and Panasonic) uses bit 10 (CLKSEL) for 1/1.  Also, newer
versions of UniPhier SoC variants use bit 16 for 1/1024.
"

Do not set the TMIO_SD_CAP_DIV1024 on Renesas R-Car platforms even if
the IP VERSION register does exist, and indicates IP version is newer
or equal to version 1.0 . The IP version 1.0 or newer does not imply
presence of the 1/1024 divider.

Since the TMIO driver is used exactly by two supported platforms, that
is Renesas R-Car and Socionext UniPhier, it is OK to check whether the
TMIO_SD_CAP_RCAR capability is not set to identify the UniPhier platform
and add the capability only on that platform.

mmc: tmio: Always check for errors after receiving an IRQ

2023-10-27T09:21:28+00:00

Unconditionally check for errors even after successful reception
of IRQ flag, since the hardware may set both an IRQ completion
flag and an error flag at the same time.

This mode of failure happens in case of an error during transfer,
in which case the hardware may set the expected IRQ completion
flag as well as error flags. The later is currently not checked
by the driver and such an error is not detected. Improve the
error detection.

mmc: tmio: Replace ifdeffery with IS_ENABLED/CONFIG_IS_ENABLED macros

2023-04-07T15:13:27+00:00

Instead of #if and #ifdef, use IS_ENABLED and CONFIG_IS_ENABLED macros.
This improves build test coverage. The CONFIG_SPL_BUILD must remain an
ifdef, as CONFIG_SPL_STACK may not always be defined, e.g. in U-Boot
proper build. No functional change.
