Anson Huang 715f5f92aa soc: imx: gpc: restrict register range for regmap access ... [ Upstream commit de2d9b5284 ] GPC registers are NOT continuous, some registers are reserved and accessing them from userspace will trigger external abort, add regmap register access table to avoid below abort: root@imx6slevk:~# cat /sys/kernel/debug/regmap/20dc000.gpc/registers [ 108.480477] Unhandled fault: imprecise external abort (0x1406) at 0xb6db5004 [ 108.487985] pgd = 42b54bfd [ 108.490741] [b6db5004] *pgd=ba1b7831 [ 108.494386] Internal error: : 1406 [#1] SMP ARM [ 108.498943] Modules linked in: [ 108.502043] CPU: 0 PID: 389 Comm: cat Not tainted 4.18.0-rc1-00074-gc9f1f60-dirty #482 [ 108.509982] Hardware name: Freescale i.MX6 SoloLite (Device Tree) [ 108.516123] PC is at regmap_mmio_read32le+0x20/0x24 [ 108.521031] LR is at regmap_mmio_read+0x40/0x60 [ 108.525586] pc : [<c059cf74>] lr : [<c059d1ac>] psr: 20060093 [ 108.531875] sp : eccf1d98 ip : eccf1da8 fp : eccf1da4 [ 108.537122] r10: ec2d3800 r9 : eccf1f60 r8 : ecfc0000 [ 108.542370] r7 : eccf1e2c r6 : eccf1e2c r5 : 00000028 r4 : ec338e00 [ 108.548920] r3 : 00000000 r2 : eccf1e2c r1 : f0980028 r0 : 00000000 [ 108.555474] Flags: nzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment none [ 108.562720] Control: 10c5387d Table: acf4004a DAC: 00000051 [ 108.568491] Process cat (pid: 389, stack limit = 0xd4318a65) [ 108.574174] Stack: (0xeccf1d98 to 0xeccf2000) Fixes: 721cabf6c6 ("soc: imx: move PGC handling to a new GPC driver") Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-08-24 13:09:19 +02:00
