| | * | | | soc/tegra: pmc: Fix reset sources and levelsJon Hunter2019-04-171-15/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5f84bb1a4099 ("soc/tegra: pmc: Add sysfs entries for reset info") added support for reading the Tegra reset source and level from sysfs. However, there are a few issues with this commit which are ... 1. The number of reset sources for Tegra210 is defined as 5 but it should be 6. 2. The number of reset sources for Tegra186 is defined as 13 but it should be 15. 3. The SoC data variables num_reset_sources and num_reset_levels are defined but never used. Fix the above by ... 1. Removing the reset source 'AOTAG' from the tegra30_reset_sources because this is only applicable for Tegra210. 2. Adding a new tegra210_reset_sources structure for Tegra210 reset sources. 3. Correct the number of reset sources for Tegra210 and Tegra186 by using the ARRAY_SIZE macro. 4. Updating the functions reset_reason_show() and reset_level_show() to check whether the value read is valid. While we are at it clean-up these functions to remove an unnecessary u32 variable.

| | |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By implementing the acquire/release protocol, the resets can be shared with other drivers that also adhere to this protocol. This will be used for example by the SOR driver to put hardware into a known good state, irrespective of whether or not the power domain can be reset.

In the RTC-only mode suspend, everything is shut down except the RTC. This makes the power consumption very low for suspend mode. To support RTC-only mode, we need to export omap_rtc_power_off_program() from the rtc driver and improve PM code to save and restore the wkup domain context. As RTC-only mode depends on the device being wired properly for things like memory, we need to also check for the machine type before we allow it. We also need to run DDR3 hardware leveling on resume. Note that there is a trivial merge conflict between the RTC branch and these changes where the RTC branch makes tm2bcd() a void function and the error handling parts can be just dropped. * tag 'omap-for-v5.2/am4-pm-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: sleep43xx: Run EMIF HW leveling on resume path memory: ti-emif-sram: Add ti_emif_run_hw_leveling for DDR3 hardware leveling soc: ti: pm33xx: AM437X: Add rtc_only with ddr in self-refresh support soc: ti: pm33xx: Move the am33xx_push_sram_idle to the top ARM: OMAP2+: pm33xx: Add support for rtc+ddr in self refresh mode rtc: OMAP: Add support for rtc-only mode Signed-off-by: Olof Johansson <olof@lixom.net>

We also need to store some information within the RTC registers so that u-boot can do the right thing at powerup. The state is entered by getting the RTC to bring the pmic_power_en line low which will instruct the PMIC to disable the appropriate power rails after putting DDR into self-refresh mode. To bring pmic_power_en low, we need to get an ALARM2 event. Since we are running from SRAM at that point, it means calculating what the next second is (via ASM) and programming that into the RTC.

While the 0xf0 mask is valid for most board, it filters out the lower 4 bits which encodes some characteristics of the chip. This patch moves the mask into the meson_gx_package_id table to be applied on each package name independently and add the correct mask for some specific entries. An example is the S905, in the vendor code the S905 is package_id different from 0x20, and S905M is exactly 0x20. Another example are the The Wetek Hub & Play2 boards using a S905-H variant, which is the S905 SoC with some licence bits enabled. These licence bits are encoded in the lower 4bits, so to detect the -H variant, we must detect the id == 0x3 with the 0xf mask.
