| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the system coprocessor managing the range allocation of the inputs to Interrupt Aggregator, it is difficult to represent the device IRQs from DT. The suggestion is to use MSI in such cases where devices wants to allocate and group interrupts dynamically. Create a MSI domain bus layer that allocates and frees MSIs for a device. APIs that are implemented: - ti_sci_inta_msi_create_irq_domain() that creates a MSI domain - ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the specified device and resource. - ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device. - ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

You can switch between the two of them by flipping a bit in the grf. The "old" implementation is the default at chip power up but isn't the one that's officially supposed to be used. ...and, in fact, the driver that gets selected in Linux using the rk3288 device tree only supports the "new" implementation. Long ago I tried to get a switch to the right IP block landed in the PWM driver (search for "rk3288: Switch to use the proper PWM IP") but that got rejected. In the mean time the grf has grown a full-fledged driver that already sets other random bits like this. That means we can now get the fix landed. For those wondering how things could have possibly worked for the last 4.5 years, folks have mostly been relying on the bootloader to set this bit. ...but occasionally folks have pointed back to my old patch series [1] in downstream kernels.

Now that the Tegra XHCI driver has been updated to properly managed the power domains, the workaround to enable the XUSB power domain early has been removed. This also means that we can now move the initialisation of the powergates into the PMC driver probe. Therefore, move the powergate initialisation into the PMC driver probe and return any errors detected. To handle any errors, functions to cleanup and remove any power-domains registered with the generic power-domain framework have been added. Finally the initialisation of the 'powergates_available' bitmask is kept in the PMC early init function to allow the legacy PMC powergate APIs to be called during early boot for enabling secondary CPUs on 32-bit Tegra devices.

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.

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.
