Add DT porperty and mechanims to set different charging voltage for different temperature. bug 1472161 Change-Id: Ia6fa3ee84cfd1f9ad8359e8249ffb268330f90cf Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Reviewed-on: http://git-master/r/379575 GVS: Gerrit_Virtual_Submit

2014-02-22power: max17040: Fix NULL pointer dereference when there is no platform_dataKrzysztof Kozlowski
commit ac323d8d807060f7c95a685a9fe861e7b6300993 upstream. Fix NULL pointer dereference of "chip->pdata" if platform_data was not supplied to the driver. The driver during probe stored the pointer to the platform_data: chip->pdata = client->dev.platform_data; Later it was dereferenced in max17040_get_online() and max17040_get_status(). If platform_data was not supplied, the NULL pointer exception would happen: [ 6.626094] Unable to handle kernel of a at virtual address 00000000 [ 6.628557] pgd = c0004000 [ 6.632868] [00000000] *pgd=66262564 [ 6.634636] Unable to handle kernel paging request at virtual address e6262000 [ 6.642014] pgd = de468000 [ 6.644700] [e6262000] *pgd=00000000 [ 6.648265] Internal error: Oops: 5 [#1] PREEMPT SMP ARM [ 6.653552] Modules linked in: [ 6.656598] CPU: 0 PID: 31 Comm: kworker/0:1 Not tainted 3.10.14-02717-gc58b4b4 #505 [ 6.664334] Workqueue: events max17040_work [ 6.668488] task: dfa11b80 ti: df9f6000 task.ti: df9f6000 [ 6.673873] PC is at show_pte+0x80/0xb8 [ 6.677687] LR is at show_pte+0x3c/0xb8 [ 6.681503] pc : [<c001b7b8>] lr : [<c001b774>] psr: 600f0113 [ 6.681503] sp : df9f7d58 ip : 600f0113 fp : 00000009 [ 6.692965] r10: 00000000 r9 : 00000000 r8 : dfa11b80 [ 6.698171] r7 : df9f7ea0 r6 : e6262000 r5 : 00000000 r4 : 00000000 [ 6.704680] r3 : 00000000 r2 : e6262000 r1 : 600f0193 r0 : c05b3750 [ 6.711194] Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel [ 6.718485] Control: 10c53c7d Table: 5e46806a DAC: 00000015 [ 6.724218] Process kworker/0:1 (pid: 31, stack limit = 0xdf9f6238) [ 6.730465] Stack: (0xdf9f7d58 to 0xdf9f8000) [ 6.914325] [<c001b7b8>] (show_pte+0x80/0xb8) from [<c047107c>] (__do_kernel_fault.part.9+0x44/0x74) [ 6.923425] [<c047107c>] (__do_kernel_fault.part.9+0x44/0x74) from [<c001bb7c>] (do_page_fault+0x2c4/0x360) [ 6.933144] [<c001bb7c>] (do_page_fault+0x2c4/0x360) from [<c0008400>] (do_DataAbort+0x34/0x9c) [ 6.941825] [<c0008400>] (do_DataAbort+0x34/0x9c) from [<c000e5d8>] (__dabt_svc+0x38/0x60) [ 6.950058] Exception stack(0xdf9f7ea0 to 0xdf9f7ee8) [ 6.955099] 7ea0: df0c1790 00000000 00000002 00000000 df0c1794 df0c1790 df0c1790 00000042 [ 6.963271] 7ec0: df0c1794 00000001 00000000 00000009 00000000 df9f7ee8 c0306268 c0306270 [ 6.971419] 7ee0: a00f0113 ffffffff [ 6.974902] [<c000e5d8>] (__dabt_svc+0x38/0x60) from [<c0306270>] (max17040_work+0x8c/0x144) [ 6.983317] [<c0306270>] (max17040_work+0x8c/0x144) from [<c003f364>] (process_one_work+0x138/0x440) [ 6.992429] [<c003f364>] (process_one_work+0x138/0x440) from [<c003fa64>] (worker_thread+0x134/0x3b8) [ 7.001628] [<c003fa64>] (worker_thread+0x134/0x3b8) from [<c00454bc>] (kthread+0xa4/0xb0) [ 7.009875] [<c00454bc>] (kthread+0xa4/0xb0) from [<c000eb28>] (ret_from_fork+0x14/0x2c) [ 7.017943] Code: e1a03005 e2422480 e0826104 e59f002c (e7922104) [ 7.024017] ---[ end trace 73bc7006b9cc5c79 ]--- Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Fixes: c6f4a42de60b981dd210de01cd3e575835e3158e Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
