| | | | | | | | | | | | | | | | | | | | 15b64fd520 introduced the ESDHC_FLAG_CACHE_SNOOPING for layerscape support, but didn't actually set it for layerscape. Add the new flag to the layerscape SoC data. Fixes: 15b64fd520 ("mci: imx-esdhc: Add layerscape support") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | mci: imx-esdhc: resolve conflicting flagsAlexander Kurz2019-03-181-4/+5
| | | | | | | | | | | | | | | | | | | | | | With commit 3354adee3920 ("mci: imx-esdhc: Add bigendian register access support") and commit 15b64fd520c2 ("mci: imx-esdhc: Add layerscape support") two ESDHC_FLAGs got assigned to already existing values. This conflict made the imx6sl usdhc appear to be big endian. Resolve this conflict by assign the new flags to the next vacant values.

| * | mci: bcm2835: use device_initcall(), not coredev.Tomaz Solc2019-02-191-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | pinctrl driver needs to be initialized before mci driver on Raspberry Pi. Otherwise the pinctrl device tree properties in the mci node are ignored. pinctrl is initialized by coredevice_initcall(), so moving mci-bcm2835 to device_initcall() ensures that it is initialized later. There is no reason for mci-bcm2835 to use coredevice_initcall(). Other mci drivers already use device_initcall(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | esdhc-xload: check for PRSSTAT_BREN only after each blockSascha Hauer2019-03-051-9/+16
| | | | | | | | | | | | | | | | | | The BREN bit tells us a watermark level sized buffer is ready for read. Instead of testing it before each FIFO read we must only check it once and then read a watermark level sized buffer. This is at least necessary on Layerscape, otherwise timeouts occur while reading the buffer. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | | | The esdhc controller is resetted once during probe by calling esdhc_reset() and once open coded in esdhc_init(). Resetting it once is enough, so drop the open coded reset from esdhc_init() and call esdhc_reset() there. With this we can remove the call to esdhc_reset() during probe.

|/ | | | | | | | | | | | | | | | | MMC cards need at least 74 clock pulses before any bus communication can occur. The i.MX SDHC controller auto-gates the clock when inactive, so if the SD enumeration is skipped for slots where we know that only a MMC card can be present (which is possible since b5289b742a89 "mmc: allow skipping SD card initialization") those inititialization clock pulses won't be sent out, resulting in command timeouts when trying to enumerate the card. Luckily the eSDHC controller has a hardware feature to send out 80 clock pulses. This has been validated to be available by checking the reference manual back to i.MX25.
