Patches to support the SoC's GPIO controller for RTL930x and RTL931x devices have been accepted upstream. Replace the current preliminary patch with the upstream ones, excluding devictree binding changes. The updated patches add GPIO IRQ balancing support on RTL930x, but this cannot be used until these devices also support SMP. Signed-off-by: Sander Vanheule <sander@svanheule.net>

Subject: [PATCH 4/6] gpio: realtek-otto: Add RTL930x support
|
|
|
|
The RTL930x SoC series has support for 24 GPIOs, with the port order
|
|
reversed compared to RTL838x and RTL839x. The RTL930x series also has
|
|
two CPUs (VPEs) and can distribute individual GPIO interrupts between
|
|
them.
