Subject: [PATCH] MIPS: ath79: add QCA955X specific glue to
|
|
ath79_device_reset_{set, clear}
|
|
|
|
commit 7d4c2af9bdbbe789fe4a93f32c5890d72cbf60a1 upstream.
|
|
|
|
The ath79_device_reset_* are causing BUG when
|
|
those are used on the QCA955x SoCs. The patch
|
|
adds the required code to avoid that.
