2020-03-31plat: imx8mp: Override the the domain suspend callbackJacky Bai
The common domain suspend callback function is not suitable for i.MX8MP due to the wait mode workaround. it will be removed together with the wait mode workaround in the future. Signed-off-by: Jacky Bai <ping.bai@nxp.com>
2020-03-31plat: imx8m: Fix the m4 enabled check for imx8mJacky Bai
On i.MX8MN & i.MX8MP, the M core enabled check should relay on the IOMUX GPR CPU_WAIT bit, when this bit is cleared, it means M core is active & running, so refine the m4 enabled check method. Signed-off-by: Jacky Bai <ping.bai@nxp.com>

2020-03-27plat: imx8mp: Add clock handling for hsiomixJacky Bai
Due to the design requirement, the HSIOMIX need to be RPM always on, so HSIOMIX need to be boot on by default. There are no way to manage the clocks when doing domain on/off, add clock handling in TF-A to resolve this issue. Signed-off-by: Jacky Bai <ping.bai@nxp.com>

2020-03-27plat: imx8m: update the wdog config for system resetJacky Bai
Current reset uses WDOG timeout function and default timeout value is set to 0.5 second. However, it is better to trigger reset immediately to speed up reboot process as well as prevent the scenario of WDOG_B toggling later than CPU reset and PMIC does NOT reset. Set the WDE bit when IMX_WDOG_B_RESET is not enabled, or reboot will fail. Signed-off-by: Jacky Bai <ping.bai@nxp.com>

2020-02-09plat: imx8mq: Add workaround code for ERR11171 on imx8mqJacky Bai
This new workaround takes advantage of the per core IMR registers in GPC in order to unmask the IRQ0, still generated by the 12bit in IOMUX_GPR register (which now remains always set), so it can only wake up one core at the time. Also, this entire workaround has now been moved here in TF-A, allowing the kernel side to be minimal. Another advantage this workaround brings is the removal of the 50us delay (which was necessary before in gic_raise_softirq in kernel) by allowing the core that is waking up to mask his own IRQ0 in the suspend finish callback. One important change here is the way the cores are woken up in dram_dvfs_handler. Since the wake up mechanism has changed from asserting the 12th bit in IOMUX_GPR and leaving the IMR1 1st bit on for each core to exactly the reverse, that is, leaving the IOMUX_GPR 12th bit always set and then masking/unmasking the IMR1 1st bit for each independent core, we need to use the imx_gpc_core_wake to wake up the cores. Also, the 50us udelay is moved to TF-A (inside imx_pwr_domain_off) from kernel (gic_raise_softirq), since the new cpuidle workaround does not need it in order to clean the IOMUX_GPC 12bit. For now, the udelay seems to be still needed in order to delay the affinity info OFF for the dying core. This is something that needs further investigation.

2020-02-09plat: imx8mq: add 100us delay after USB OTG SRC bit 0 clearJacky Bai
After the SRC bit clear, we must wait for a while to make sure the operation is finished. And don't enable all the PU domains by default. for USB OTG, the limitations are: 1. before system clock configuration. ipg clock runs at 12.5MHz. delay time should longer than 82us. 2. after system clock configuration. ipg clock runs at 66.5MHz. delay time should longer than 15.3us. so add udelay 100 to safely clear the SRC bit 0.
