Subject: dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G3L SoC
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3aa78b828e5d68bc8231a70ed295bcc6227bc611;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G3L SoC

Document RZ/G3L (R9A08G046) IRQC. The IRQC block on the RZ/G3L SoC is
nearly identical to that found on the RZ/G3S SoC, with the following
differences: it supports more external interrupts and GPT error
interrupts, and adds registers for GPT/MTU interrupt selection and shared
interrupt selection between external interrupt and TINT. A new compatible
string "renesas,r9a08g046-irqc" is therefore introduced for the RZ/G3L
SoC.
