Javier Martinez Canillas ba1b53feb8 regmap: Fix DT endianess parsing logic ... Commit d647c19951 ("regmap: add DT endianness binding support.") added support to parse the device endianness from the device tree but unfortunately the added logic doesn't have the same semantics than the old code. This leads to a NULL dereference pointer error when these properties are not provided by the Device Tree: Unable to handle kernel NULL pointer dereference at virtual address 00000044 pgd = c0004000 [00000044] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 5 PID: 1 Comm: swapper/0 Not tainted 3.17.0-rc1-next-20140818ccu #671 task: ea412800 ti: ea484000 task.ti: ea484000 PC is at regmap_update_bits+0xc/0x5c The problem is that platforms that rely on the default value now gets different values due two related issues in the current code: a) It only parses the endianness from DT for the regmap registers and not for the regmap values but it checks unconditionally in both cases if the resulting endiannes is REGMAP_ENDIAN_NATIVE. b) REGMAP_ENDIAN_NATIVE is not even a valid DT property according to the regmap DT binding documentation so it shouldn't be set.
