Subject: [PATCH] phy: rockchip-snps-pcie3: only look for rockchip,pipe-grf on
|
|
rk3588
|
|
|
|
The rockchip,pipe-grf property is only used on rk3588, but not on
|
|
rk3568. Therefore this property is not present on rk3568 devices,
|
|
leading to the following message:
|
|
|
|
rockchip-snps-pcie3-phy fe8c0000.phy: failed to find rockchip,pipe_grf regmap
|
|
|
|
Fix that by only looking for this property on rk3588.
|
|
