For simplicity we don't bother with the register defaults tables but instead read the defaults from the device - regmap is capable of doing this, unlike our old cache infrastructure. This saves a lot of code and allows us to cache the device revision information too.

However, because MFD devices have a different address space and the ab8500 and db8500 both use I2C to communicate, this causes issues with address translation during execution of of_platform_populate(). So the solution is to make the MFD core aware of Device Tree and have it assign the correct node pointers instead. To make this work the MFD core also needs to be awere of IRQ domains, as Device Tree insists on IRQ domain compatibility. So, instead of providing an irq-base via platform code, in the DT case we simply look up the IRQ domain and map to the correct virtual IRQ.

On those SoC the SPI hardware will deassert CS line as soon as the SPI FIFO is empty. The MC13xxx hardware is very sensitive to CS line change as it corrupts the transfer if CS is deasserted in the middle of a register read or write. It is not possible to use the CS line as a GPIO on some SoC, so we need to workaround this by implementing a single SPI transfer to access the PMIC.

It won't read the enable/disable parameter in WMI command, but just iterates the wifi/bt's status described below 1st. enable wifi, enable bt 2nd. disable wifi, enable bt 3rd. enable wifi, disable bt 4th. disable wifi, disable bt That will totally mess up the rfkill status, since we will try to read wifi and bt's status and reset it again while booting up. To avoid this, these machines should set the wapf value to 4, that will let software totally control the wifi/bt's status and BIOS will do nothing instead of sending out the 0x88(KEY_RFKILL) event instead of 0x5e(wifi enable), 0x5f(wifi diable), 0x7d(bt enable), and 0x7e(bt disable) through WMI. With this patch[1], it will handle the KEY_RFKILL event correctly and will block/unblock wifi and bt together. 1. https://lkml.org/lkml/2012/5/21/75 Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

After discussing with ASUS' BIOS engineer, they say wake on lid open doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same device ID with deep S3(0x00120031), and the deep S3(resume on lid open) is disable by default.

Currently drivers where using acpi_video_unregister() directly but: - That didn't respect any acpi_backlight=[video|vendor] parameter provided by the user. - Any later call to acpi_video_register() would still re-load the generic video module (and some gpu drivers are doing that). This patch fix those two issues. Signed-off-by: Corentin Chary <corentin.chary@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
