38f25b125e OMAP4+: Force DDR in self-refresh after warm reset
Errata ID:i727

Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0]
REG_REFRESH_RATE parameter taking into account frequency of the device.
When a warm reset is applied on the system, the OMAP processor restarts
with another OPP and so frequency is not the same. Due to this frequency
change, the refresh rate will be too low and could result in an unexpected
behavior on the memory side.

Workaround:
The workaround is to force self-refresh when coming back from the warm reset
with the following sequence:
• Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2
• Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0
• Do a dummy read (loads automatically new value of sr_tim)
This will reduce the risk of memory content corruption, but memory content
can't be guaranteed after a warm reset.

This errata is impacted on
OMAP4430: 1.0, 2.0, 2.1, 2.2, 2.3
OMAP4460: 1.0, 1.1
OMAP4470: 1.0

5c23712dbd i.MX6 USDHC: Use the ESDHC clock
The commit "i.mx: fsl_esdhc: add the i.mx6q support" (4692708d) introduces
support for the i.MX6Q MMC host controller USDHC.

MXC_IPG_PERCLK sets the clock to 66MHz. This seems to be the default clock
of the ESDHC IP found in < i.MX6 silicon. However, the default clock for the USDHC
IP found in i.MX6 is 200MHz (MXC_ESDHC_CLK). This difference will cause a 3 times
higher clock on SD_CLK than expected (see fsl_esdh.c -> set_sysctl()).

a3c3fabb0f arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xx
In warm reset conditions on OMAP36xx/AM/DM37xx the rom code
incorrectly sets the DPLL4 clock input divider to /6.5 which
is an invalid value unless the input clock is 13MHz. When a JTAG
emulator is attached, a warm reset is necessary after the emulator
gains control of the process. This results in a loss of serial
output due to the invalid DPLL4 settings.

This patch fixes the issue by resetting the DPLL4 clock input
divider to /1 when the input clock is not 13MHz. AM/DM37x TRM
section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only
used when the input clock is 13MHz.
