mmc: dwmmc: Change designware MMC 'clksel' callback function to return status

2021-01-15T09:48:36Z

Change 'clksel' callback function to allow the code to return a status. This patch is a preparation for enabling Arm-Trusted-Firmware (ATF) in Intel SoC FPGA. This patch does not change functionality. When using Arm-Trusted-Firmware (ATF) in Intel SoC FPGA, the MMC clock related register is secure register which is required to be written via SMC/PCSI call. It is possible that U-Boot fail to write the register if there is unexpected error between U-Boot and ATF. As a result, there maybe signal integrity on MMC connection due to clock. So, the code should reports error to user when 'clksel' fail. Signed-off-by: Siew Chin Lim

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

2020-12-13T23:51:09Z

Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08Z

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

common: Drop linux/bitops.h from common header

Move this uncommon header out of the common header. Signed-off-by: Simon Glass

common: Drop net.h from common header

2020-05-18T21:33:31Z

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass

mmc: dwmmc: Poll for iDMAC TX/RX interrupt

Poll for iDMAC TX/RX interrupt before disable DMA. This to prevent disable DMA before data is transfer completed. Signed-off-by: Ley Foon Tan

mmc: dw_mmc: Add RCRC handling

2018-11-10T13:16:30Z

This patch adds check for command response CRC failure. The driver is currently ignoring CRC check failure on command resposes which have CRC atteched to it, which can be potentially dangerous. Even more grueling problem happens when the command response is followed by data transfer though, as in that case, the dwmci_data_transfer() function will spin until it reaches the 240s timeout.

mmc: dw_mmc: check fifo status with a timeout in fifo mode

2018-10-02T07:35:09Z

While trying to enable the dw_mmc on rk3188 I managed to confuse and hang the dw_mmc controller into not delivering further data. The fifo state never became ready and the driver was iterating in the while loop reading 0-byte packets forever. So inspired by how other implementations handle this, check the fifo- state beforhand and add a timeout to catch any glaring fifo issues without hanging uboot altogether.
