2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

>From OMAP3 SoCs (OMAP3, OMAP4, OMAP5, AM572x, AM571x), the DAT/CMD lines reset procedure section in TRM suggests to first poll the SRD/SRC bit until it is set to 0x1. But looks like that bit is never set to 1 and there is an observable delay of 1sec everytime the driver tries to reset DAT/CMD. (The same is observed in linux kernel). Reduce the time the driver waits for the controller to set the SRC/SRD bits to 1 so that there is no observable delay.

2018-02-19mmc: omap_hsmmc: Workaround for errata id i802Jean-Jacques Hiblot
According to errata i802, DCRC error interrupts (MMCHS_STAT[21] DCRC=0x1) can occur during the tuning procedure. The DCRC interrupt, occurs when the last tuning block fails (the last ratio tested). The delay from CRC check until the interrupt is asserted is bigger than the delay until assertion of the tuning end flag. Assertion of tuning end flag is what masks the interrupts. Because of this race, an erroneous DCRC interrupt occurs. The suggested workaround is to disable DCRC interrupts during the tuning procedure which is implemented here.

"ti,dual-volt" is used in linux kernel to set the voltage capabilities. For host controller dt nodes that doesn't have "ti,dual-volt", it's assumed 1.8v is the io voltage.

Commit 4f425280fa71 ("mmc: fsl_esdhc: Allow all supported prescaler values") made it possible to set SYSCTL.SDCLKFS to 0 in SDR mode on i.MX, thus bypassing the SD clock frequency prescaler, in order to be able to get higher SD clock frequencies in some contexts. However, that commit missed the fact that this value is illegal on the eSDHCv3 instance of the i.MX53. This seems to be the only exception on i.MX, this value being legal even for the eSDHCv2 instances of the i.MX53. Fix this issue by changing the minimum prescaler value for the single instance of the i.MX53 eSDHCv3 controller.
