| * ARM: imx: fsl_esdhc: fix usage of low 4 bits of sysctl registerEric Nelson2016-01-031-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The low four bits of the SYSCTL register are reserved on the USDHC controller on i.MX6 and i.MX7 processors, but are used for clocking operations on earlier models. Guard against their usage by hiding the bit mask macros on those processors. These bits are used to prevent glitches when changing clocks on i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7. >From the i.MX6DQ RM: To prevent possible glitch on the card clock, clear the FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS or DVS in System Control Register) or setting RSTA bit.

| | | | | | | | | | | | | | | | | | | | | | | | After silencing the prints which were generated when reconfiguring the clock of the SD/MMC bus, surprisingly, the driver stopped working such that every attempt to use the SD/MMC bus caused the CPU to get totally stuck hard. It turns out that the prints generated a short delay, which was necessary for the CPU to reconfigure the clock without getting stuck.
