Change the hardware reset gpio to 'GPIO6_IO15' for mipi dsi to
allow fec2 and mipi dsi can run at the same time. This needs
some hardware rework as follows:
"
1. Replace R631 with 100K resistor;
2. Remove D14, D24;
3. Solder the Cathode of the diode to R471,
you can use BAT54HT1(ONSEMI) or NSR0320MW2T1G(ONSEMI);
4. Solder the wire to the Anode end of the diode;
5. Scrape the solder mask(Green oil) of the MIPI Reset via,
then solder the end of the wire to the via.

The 32 bpp pixel format which is passed to pxp should be
'PXP_PIX_FMT_RGB32' instead of 'PXP_PIX_FMT_RGB24', since
only 'PXP_PIX_FMT_RGB32' can be recognized by lcdif.Signed-off-by: Fancy Fang

with CONFIG_HZ=100, the precision of jiffies is 10ms, and the

there is a time window between __mmc_send_status() and time_afer(),
on some eMMC chip, the timeout_ms is only 10ms, if this thread was
scheduled out during this period, then, even card has already changes
to transfer state by the result of CMD13, this part of code also treat
it to timeout error.
So, need calculate timeout first, then call __mmc_send_status(), if
already timeout and card still in programing state, then treat it to
the real timeout error.Signed-off-by: Chaotian Jing

Our Reference Manual has a mistake, for the register SYS_CTRL,the
DTOCV(bit 19~16) means the data timeout counter value. When DTOCV
is set to 0xF, it means SDCLK << 29, not SDCLK << 28.This patch correct this in our usdhc driver.

During suspend, as 24MHz will be disabled, but system counter
needs to be running in order to maintain accurate clock source,
so we need to switch system counter's clock from base clock(24MHz)
to alternate clock(32K) before system enter STOP mode, otherwise,
the suspend time will NOT be counted into system time when issue
a "date" command.Signed-off-by: Anson Huang

This reverts commit 312979d1fcbd068d4ba0f461e974e7cbcc889548.
When busfreq is at low bus mode, which is 24MHz, it means DDR/AHB/AXI
will drop to 24MHz. At the same time, when in low busfreq mode, cpuidle
can be in low power idle, DRAM will be put into self-refresh and DRAM IO
will in low power mode to save power, so DMA will NOT work.So all peripherals that needs DMA, need to request bus freq to high
setpoint when it is active.Signed-off-by: Haibo Chen

The assert gpio comes from 'gpio_spi' module, so the framebuffer
depends on the 'gpio_spi' driver loading. And in the case that
the framebuffer driver is loaded earlier than the 'gpio_spi'
driver, the gpio asserting will fail. So handle this gpio in
the framebuffer driver and add deferred probed support.Signed-off-by: Fancy Fang

When Mega/Fast Mix off in DSM mode, RDC recovery needs PCIe/PXP/EIM
clock to be enabled, otherwise, with M4 enabled, DSM resume will fail.We only enable them before entering DSM and hardware will disable

For i.MX7D, current runtime clock management code will skip all
PLL/PFD/GATE enable/disable when M4 is enabled, this is NOT good
for power number in low power idle and audio playback, as M4 only
uses one high speed PFD which is from system PLL, it is never
disabled runtimely, so we can just enable the hardware operation of
PLL/PFD/GATE for A7.Signed-off-by: Anson Huang

To i.MX7D and i.MX6ULL, we need to support multiple iomux controller,
but we only have one imx_pinctrl_desc with type static. This means
different iomux controller share one imx_pinctrl_desc variable.The value filled into imx_pinctrl_desc when probing the first iomuxc
node will be overriden when probing the second one.This will incur errors, such as
'mx7d-pinctrl 30330000.iomuxc: could not map pin config for
"MX7D_PAD_LCD_DATA00"'In this patch, dynamically allocate imx_pinctrl_desc for each iomux
controller to fix the issue.Signed-off-by: Peng Fan
