ARM: imx: Remove PU power operation for i.MX6QP The GPC power domain driver add GENPD_FLAG_RPM_ALWAYS_ON to the i.MX6QP's PU power domain flag, that means it is always ON for runtime PM but can be OFF during suspend, so no need to explicitly power ON/OFF PU power for i.MX6QP during suspend/resume to avoid below dump: Unable to handle kernel NULL pointer dereference at virtual address 00000044 pgd = 20824a30 [00000044] *pgd=4e36d831 Internal error: Oops: 17 [#1] SMP ARM Modules linked in: CPU: 0 PID: 732 Comm: sh Tainted: G W 5.3.0-rc3-next-20190809-01770-g0a0b3ec-dir3 Hardware name: Freescale i.MX6 Quad/DualLite (Device Tree) PC is at regmap_update_bits_base+0x10/0x74 LR is at imx6_pm_domain_power_on+0xbc/0x1b4 pc : [<c070887c>] lr : [<c05e18e4>] psr: 600001d3 sp : e9339d68 ip : e9338000 fp : c1a24158 r10: c1308b08 r9 : 00000260 r8 : c1308b08 r7 : c1426120 r6 : c1426120 r5 : c1373580 r4 : 00000000 r3 : 00000001 r2 : 00000001 r1 : 00000260 r0 : 00000000 Flags: nZCv IRQs off FIQs off Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 3949404a DAC: 00000051 Process sh (pid: 732, stack limit = 0x8ba716d6) Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
