[PATCH-v4 00/11] i2c: pxa: Fixes, cleanup and support for pxa910 family

[Vaibhav Hiremath <vaibhav.hiremath@linaro.org>]

This patch series fixes bugs/warnings, cleans up the code and adds
support for PXA910 family of devices to PXA I2C bus driver.

There has been one attempt made sometime back in 2012 to upstream
some of the patches from below list, but did not get follow up later.
I have consolidated all the patches, cleaned them up, splited into
logical changes, added new patches and submitting it now.

I tried to maintain authorship & Signoff except where I did some
significant changes to the code/logic.

Testing:
  - Basic testing on PMIC device on I2C-0 interface
  - Boot tested on platform based on PXA1928
  - Probe is successfully passing
  - Read few registers of PMIC (RTC, ID, etc...) during boot

  - [PATCH 06/11] Removed unnecessary dev_err on devm_kzalloc() check
  - [PATCH 06/11] Removed return check on platform_get_resource(), as 
    devm_ioremap_resource() does it for us.
    Also, brought up the devm_ioremap_resource() function call in the execution
    sequence, as no point in delaying it if we do not have resource.
    It make sense, after this change.
  - [PATCH 04/11] Typecast changed to 'enum pxa_i2c_types'
    Also updated the subject line "Removed ==> Fix"
