i2c: ocores: add i2c driver for OpenCores I2C controller

2020-11-28T07:30:41Z

Add support for the OpenCores I2C controller IP core (See http://www.opencores.org/projects.cgi/web/i2c/overview). This driver implementation is inspired from the Linux OpenCores I2C driver available. Thanks to Peter Korsgaard for writing Linux OpenCores I2C driver.

i2c: designware_i2c: Don't warn if no reset controller

2020-11-28T07:30:41Z

At present if CONFIG_RESET is not enabled, this code shows a warning: designware_i2c_ofdata_to_platdata() i2c_designware_pci i2c2@16,0: Can't get reset: -524 Avoid this by checking if reset is supported, first.

i2c: mvtwsi: disable i2c slave also on Armada 8k

2020-11-28T07:17:16Z

The hidden I2C slave is also present on the Armada 8k AP806. Testing shows that this I2C slave causes the same issues as Armada 38x. Disabling that I2C slave fixes all these issues. I2C blocks on the Armada 8k CP110 are not affected. Extend the I2C slave disable to Armada 8k as well. Cc: Stefan Roese Signed-off-by: Baruch Siach

mmc: fsl_esdhc: make sure delay chain locked for HS400

2020-11-28T02:39:44Z

For eMMC HS400 mode, the DLL reset is a required step for mmc rescan. This step has not been documented in reference manual, but the RM will be fixed sooner or later. In previous commit to support eMMC HS400, db8f936 mmc: fsl_esdhc: support eMMC HS400 mode the steps to configure DLL could be found in commit message, 13. Set DLLCFG0[DLL_ENABLE] and DLLCFG0[DLL_FREQ_SEL]. 14. Wait for delay chain to lock. these would be fixed as, 13. Set DLLCFG0[DLL_ENABLE] and DLLCFG0[DLL_FREQ_SEL]. 13.1 Write DLLCFG0[DLL_RESET] to 1 and wait for 1us, then write DLLCFG0[DLL_RESET] 14. Wait for delay chain to lock. This patch is to add the step of DLL reset, and make sure delay chain locked for HS400.

mmc: fsl_esdhc: set sysctl register for clock initialization

2020-11-28T02:39:44Z

The initial clock setting should be through sysctl register only, while the mmc_set_clock() will call mmc_set_ios() introduce other configurations like bus width, mode, and so on. Signed-off-by: Yangbo Lu Reviewed-by: Jaehoon Chung

mmc: Add some helper functions for retrying on error

2020-11-28T02:39:44Z

All of the existing quirks add retries to various calls of mmc_send_cmd. mmc_send_cmd_quirks is a helper function to do this retrying behavior. It checks if quirks mode is enabled, and if a specific quirk is activated it retries on error. This also adds mmc_send_cmd_retry, which retries on error every time (instead of if a quirk is activated). Signed-off-by: Sean Anderson Reviewed-by: Jaehoon Chung Reviewed-by: Jaehoon Chung
