This should now work properly with power domain dependencies. With "apple,always-on" removed from ps_pmp add it as dependency for the dcp* power-domains. Fixes dcp crashes on power state changes. TODO: investigate if it is enough to power ps_pmp on during SetPowerState calls. Signed-off-by: Janne Grunau <j@jannau.net>

Make sure the channel order mirrors that of the playback PCM. arm64: dts: apple: t600x-j314-j316: Zero out unused speaker sense slots Make one left codec and one right codec zero out the unused slots on their respective speaker sense buses. Internally, inside the SoC, the left and right sense buses are ORed, and zeroing-out the unused slots on one bus is required so as not to corrupt the data on the other. arm64: dts: apple: t600x: describe shared SDZ GPIO for tas2764 machines with the tas2764 amp codec share a GPIO line for asserting/deasserting the SDZ pin on the chips. describe this as a regulator to facilitate chip reset on suspend/resume Signed-off-by: Martin Povišer <povik+lin@cutebit.org> Co-developed-by: Hector Martin <marcan@marcan.st> Signed-off-by: Hector Martin <marcan@marcan.st> Co-developed-by: James Calligeros <jcalligeros99@gmail.com> Signed-off-by: James Calligeros <jcalligeros99@gmail.com>

The Mac Studio M1 Max (t6001) model has a built-in USB3 hub. This hub has a firmware flash which is also connected to an AP SPI controller. The hub starts out in reset and the host is expected to bring it out of reset, potentially after upgrading/validating the firmware. We won't be doing anything with the firmware, so just use gpio-hog to flip the two GPIOs needed to bring up the hub chip. Signed-off-by: Hector Martin <marcan@marcan.st>
The dcp co-processor crashes on HDMI unplug while it apparently tries to notify pmp. Handle "notify_pmp" as a parent dependency for "ps_disp0_fe" and "ps_dispext_fe". Signed-off-by: Janne Grunau <j@jannau.net>

The display system is initialized by the bootloader to provide a simple framebuffer at startup. Memory for the framebuffer and heap for the display co-processor are alreay mapped through the IOMMU. IOMMU intialization must preserve this mappings to avoid crashing the display co-processor. The exisitng mappings are caried in the devicetree. They are applied during device attach to ensure the IOMMU framework is aware of these mapping. Mappings are filled by m1n1 during boot.

Apple M3 Pro and Max devices are using 'gp00' keys for GPIO in addition to 'gP00' keys. Add a second compatible to handle this keys with an additional macsmc-gpio instance. Signed-off-by: Janne Grunau <j@jannau.net>
Add support for SMC GPIO keys with a lower letter 'p' via the "apple,smc-low-gpio" compatible. This adds support for a second macsmc-gpio controller using 'gp00' keys. These keys are used on Apple M3 Pro and Max MacBooks in the controller for keyboard and trackpad and for the built-in DisplayPort to HDMI converter. Signed-off-by: Janne Grunau <j@jannau.net>

The internal keyboard and trackpad HID on MacBook variants of the Apple M3 (t8122) SoC are connected through a Apple -developed protocol called DockChannel and mediated by a coprocessor known as the Multi-Touch Processor (MTP). This commit adds the nessecary device tree nodes to the M3's device tree for internal HID to work. It is disabled by default, to be enabled only in MacBook board files where it is tested and confirmed to work.

does moving ps_apcie_sys_st to the pmp_report subnode causes any issues? Even if I think I'd still prefer
