2014-01-22x86: Don't add new __cpuinit users to Merrifield platform codePaul Gortmaker2-2/+2
Commit bc20aa48bbb3068224a1c91f8332971fdb689fad ("x86, intel-mid: Add Merrifield platform support") added new instances of __cpuinit usage. We removed this a couple versions ago; we now want to remove the compat no-op stubs. Introducing new users is not what we want to see at this point in time, as it will break once the stubs are gone. This also fixes an out of sync __init vs. __cpuinit -- as the former is real, and the latter is a no-op; hence it would have been a section mismatch. Cc: Fei Yang <[email protected]> Cc: H.

2014-01-16x86, intel-mid: Check get_gpio_by_name() error code on platform codeDavid Cohen7-8/+12
This patch does cleanup on all intel mid platform code that uses gpio_get_by_name() function. From now on they should check for any error code instead of only hardcoded -1. There are no functional changes from this change. Signed-off-by: David Cohen <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: H. Peter Anvin <[email protected]>
2014-01-16x86, intel-mid: sfi_handle_*_dev() should check for pdata error codeDavid Cohen1-0/+6
When Intel MID finds a match between SFI table from FW and registered SFI devices, it will always register a device regardless the platform code was successful or not. This patch adds an extra option for platform code to return error code and abort device registration on SFI table parsing. This patch does not contain any functional changes for current intel mid platform code.

2014-01-06x86: Delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-10-17intel_mid: Move platform device setups to their own platform_<device>.* filesDavid Cohen24-429/+959
As Intel rolling out more SoC's after Moorestown, we need to re-structure the code in a way that is backward compatible and easy to expand. This patch implements a flexible way to support multiple boards and devices. This patch does not add any new functional support. It just refactors the existing code to increase the modularity and decrease the code duplication for supporting multiple soc's and boards. Currently intel-mid.c has both board and soc related code in one file. This patch moves the board related code to new files and let linker script to create SFI devite table following this: 1. Move the SFI device specific code to arch/x86/platform/intel-mid/device-libs/platform_<device>.* A new device file is added for every supported device. This code will get conditionally compiled by using corresponding device driver CONFIG option. 2. Move the device_ids location to .x86_intel_mid_dev.init section by using new sfi_device() macro. This patch was based on previous code from Sathyanarayanan Kuppuswamy.

2013-10-17intel-mid: sfi: Allow struct devs_id.get_platform_data to be NULLDavid Cohen1-4/+7
Intel mid sfi code doesn't need struct devs_id.get_platform_data != NULL. If the callback is not set, just assume there is no platform_data.

2013-10-17intel_mid: Moved SFI related code to sfi.cKuppuswamy Sathyanarayanan3-450/+488
Moved SFI specific parsing/handling code to sfi.c. This will enable us to reuse our intel-mid code for platforms that supports firmware interfaces other than SFI (like ACPI).

2013-10-17intel_mid: Added custom device_handler supportKuppuswamy Sathyanarayanan1-34/+40
This patch provides a means to add custom handler for SFI devices. If you set device_handler as NULL in device_id table standard SFI device handler will be used. If its not NULL custom handler will be called.

2013-10-17intel_mid: Refactored sfi_parse_devs() functionKuppuswamy Sathyanarayanan1-70/+71
SFI device_id[] table parsing code is duplicated in every SFI device handler. This patch removes this code duplication, by adding a seperate function get_device_id() to parse through the device table. Also this patch moves the SPI, I2C, IPC info code from sfi_parse_devs() to respective device handlers.

2013-10-17intel_mid: Renamed *mrst* to *intel_mid*Kuppuswamy Sathyanarayanan3-60/+59
mrst is used as common name to represent all intel_mid type soc's. But moorsetwon is just one of the intel_mid soc. So renamed them to use intel_mid. This patch mainly renames the variables and related functions that uses *mrst* prefix with *intel_mid*. To ensure that there are no functional changes, I have compared the objdump of related files before and after rename and found the only difference is symbol and name changes.

2013-10-17intel_mid: Renamed *mrst* to *intel_mid*Kuppuswamy Sathyanarayanan4-0/+1560
Following files contains code that is common to all intel mid soc's. So renamed them as below. mrst/mrst.c -> intel-mid/intel-mid.c mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c pci/mrst.c -> pci/intel_mid_pci.c Also, renamed the corresponding header files and made changes to the driver files that included these header files. To ensure that there are no functional changes, I have compared the objdump of renamed files before and after rename and found that the only difference is file name change.
