2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine1-1/+1
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <[email protected]> Signed-off-by: Bjorn Helgaas <[email protected]>
2014-01-21ipc: add intel-mid's pci id macrosDavid Cohen1-4/+9
For readability matters, this patch replaces the hardcoded pci ids by human readable macros. Signed-off-by: David Cohen <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>
2014-01-21ipc: simplify platform data approachDavid Cohen1-44/+40
This patch removes the unnecessary enum for platform type to handle the array of pdatas. We can set pdata directly to pci_device_id struct instead. Signed-off-by: David Cohen <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>
2013-11-20ipc: Added support for IPC interrupt modeKuppuswamy Sathyanarayanan1-3/+45
This patch adds support for ipc command interrupt mode. Also added platform data option to select 'irq_mode' irq_mode = 1: configure the driver to receive IOC interrupt for each successful ipc_command. irq_mode = 0: makes driver use polling method to track the command completion status.

2013-11-20ipc: Added platform data structureKuppuswamy Sathyanarayanan1-8/+29
Since the same ipc driver can be used by many platforms, using macros for defining ipc_base and i2c_base addresses is not a scalable approach. So added a platform data structure to pass this information.

2013-10-17intel_mid: Renamed *mrst* to *intel_mid*Kuppuswamy Sathyanarayanan1-1/+1
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 Sathyanarayanan1-1/+1
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.

2011-12-21driver-core: remove sysdev.h usage.Kay Sievers1-1/+1
The sysdev.h file should not be needed by any in-kernel code, so remove the .h file from these random files that seem to still want to include it. The sysdev code will be going away soon, so this include needs to be removed no matter what.

2010-11-09x86/mrst: Add SFI platform device parsing codeFeng Tang1-0/+5
SFI provides a series of tables. These describe the platform devices present including SPI and I²C devices, as well as various sensors, keypads and other glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c) This patch is a merge of the core elements and relevant fixes from the Intel development code by Feng, Alek, myself into a single coherent patch for upstream submission. It provides the needed infrastructure to register I2C, SPI and platform devices described by the tables, as well as handlers for some of the hardware already supported in kernel. The 0.8 firmware also provides GPIO tables. Devices are created at boot time or if they are SCU dependant at the point an SCU is discovered. The existing Linux device mechanisms will then handle the device binding. At an abstract level this is an SFI to Linux device translator. Device/platform specific setup/glue is in this file. This is done so that the drivers for the generic I²C and SPI bus devices remain cross platform as they should.
