pico-imx7d: Correct uart clock root

2019-06-11T08:42:48Z

Correct uart clock root ID. Incorrect ID may result the clock is gated because rate value 0 is returned in imx_get_uartclk() The ID can be ignored if CONFIG_SKIP_LOWLEVEL_INIT is not enabled because init_clk_uart() will enable all uart clocks in that case. Signed-off-by: Jun Nie

imx: mx7: Skip secure init in arch_cpu_init

2019-06-11T08:42:48Z

Skip secure related initialization in arch_cpu_init if low level init is skipped. Because these should be done in early stage firmware, such as ARM trusted firmware. Signed-off-by: Jun Nie

video: mxsfb: add DM_VIDEO support

2019-06-04T21:25:54Z

Extend the driver to build with DM_VIDEO enabled. DTS files must additionally include 'u-boot,dm-pre-reloc' property in soc and child nodes to enable driver binding to mxsfb device. Signed-off-by: Igor Opaniuk

mx7: Do not call lcdif_power_down() in the SPL case

2019-01-28T11:53:21Z

Like it was done on imx6 in commit 9236269de57d ("imx: mx6: Fix implementantion reset_misc") Do not call lcdif_power_down() in the SPL case to fix the following build error: LD spl/u-boot-spl MKIMAGE u-boot.img arch/arm/mach-imx/built-in.o: In function `reset_misc': /home/fabio/ossystems/u-boot/arch/arm/mach-imx/mx7/soc.c:372: undefined reference to `lcdif_power_down' scripts/Makefile.spl:375: recipe for target 'spl/u-boot-spl' failed Signed-off-by: Fabio Estevam Signed-off-by: Otavio Salvador Signed-off-by: Fabio Estevam Signed-off-by: Otavio Salvador Reviewed-by: Peng Fan

imx: mx7: avoid some initialization if low level is skipped

2018-10-22T12:37:28Z

We can have the case where u-boot is launched after some other low level enabler, like for example when u-boot runs after arm-trusted-firmware and/or optee. So, because of that we may need to jump the initialization of some IP blocks even because we may no longer have the permission for that. So, if the config option to skip low level init is set disable also timer, board and csu initialization.

imx: mx7: fix potential overflow in imx_ddr_size()

2018-10-09T16:32:47Z

The imx_ddr_size() function may overflow as it is possible to kind of over provision the DDR controller. Fix this by capping it to 2 GB which is the maximum allowed size as per reference manual. Signed-off-by: Marcel Ziswiler Reviewed-by: Fabio Estevam

imx: mx7: add system suspend/resume support

2018-09-04T06:47:23Z

This patch adds system suspend/resume support, when linux kernel enters deep sleep mode, SoC will go into below mode: - CA7 platform goes into STOP mode; - SoC goes into DSM mode; - DDR goes into self-refresh mode; - CPU0/SCU will be powered down. When wake up event arrives: - SoC DSM mdoe exits; - CA7 platform exit STOP mode, SCU/CPU0 power up; - Invalidate L1 cache; - DDR exit self-refresh mode; - Do secure monitor mode related initialization; - Jump to linux kernel resume entry. Belwo is the log of 1 iteration of system suspend/resume: [ 338.824862] PM: suspend entry (deep) [ 338.828853] PM: Syncing filesystems ... done. [ 338.834433] Freezing user space processes ...

[ 339.398990] PM: suspend exit The resume entry function has to initialize stack pointer before calling C code, otherwise there will be an external abort occur, in additional, invalidate L1 cache must be done in secure section as well, so this patch also adds assembly code back and keep it as simple as possible.

imx: mx7: add gpc initialization for low power mode

2018-09-04T06:47:23Z

Add i.MX7D GPC initialization for low power mode support like system suspend/resume from linux kernel: - Pending IOMUXC IRQ to workaround GPC state machine issue; - Mask all GPC interrupts for M4/C0/C1; - Configure SCU timing; - Configure time slot ack; - Configure C0/C1 power up/down timing; - Configure wakeup source mechanism; - Disable DSM/RBC related settings.

imx: mx7: psci: improve cpu hotplug flow

2018-09-04T06:47:23Z

This patch improves cpu hotplug, previous cpu_off implementation is NOT safe, a CPU can NOT power down itself in runtime, it will cause system bus hang due to pending transaction. So need to use other online CPU to kill it when it is ready for killed. Here use SRC parameter register and a magic number of ~0 as handshake for killing a offline CPU, when the online CPU checks the psci_affinity_info, it will help kill the offline CPU according to the magic number stored in SRC parameter register.
