This patch adds a new MFD driver for the RDC321x southbridge. This southbridge
|
|
||||||
is always present in the RDC321x System-on-a-Chip and provides access to some
|
|
||||||
GPIOs as well as a watchdog. Access to these two functions is done using the
|
|
||||||
southbridge PCI device configuration space.

|
||||||
Changes from v2:
|
|
||||||
- pass the pci_dev pointer to MFD cell drivers as platform_data
|
|
||||||
- remove the printk(KERN_ERR and use dev_err instead
|
|
||||||
- removed pci_dev accessors
|
|
||||||
- use DEFINE_PCI_DEVICE_TABLE

Changes from v2:
|
|
||||||
- initialize spinlock earlier
|
|
||||||
- do not declare and assign gpch variables on the same line
|
|
||||||
- use the pci_dev pointer passed as platform data
|
|
||||||
- replaced rdc321x_pci_{read,write}

The RDC321x MFD southbridge driver will pass a reference to the southbridge
|
|
||||||
PCI device which should be used by the watchdog driver for its operations.
|
|
||||||
This patch converts the watchdog driver to use the pci_dev pointer and make use
|
|
||||||
of the base register resource which is passed along with the platform device.

Changes from v2:

- replaced rdc321x_pci_{read,write}
|

- use the pci_dev pointer passed as platform_data

+Introduction
|
|
||||||
+============
|
|
||||||
+
|
|
||||||
+RDC (http://www.rdc.com.tw) have been manufacturing x86-compatible SoC
|
|
||||||
+(system-on-chips) for a number of years. They are not the fastest of
|
|
||||||
+CPUs (clock speeds ranging from 133-150MHz) but 486SX compatibility
|
|
||||||
+coupled with very low power consumption[1] and low cost make them ideal
|
|
||||||
+for embedded applications.
|
|
||||||
+
|
|
||||||
+
|
|
||||||
+Where to find
|
|
||||||
+=============
|
|
||||||
+
|
|
||||||
+RDC chips show up in numerous embedded devices, but be careful since
|
|
||||||
+many of them will not run Linux 2.6 without significant expertise.
|
|
||||||
+
|
|
||||||
+There are several variants of what the linux kernel refers to generically
|
|
||||||
+as RDC321X: R8610, R321x, S3282 and AMRISC20000.
|
|
||||||
+
|
|
||||||
+R321x: Found in various routers, see the OpenWrt project for details,
|
|
||||||
+ http://wiki.openwrt.org/oldwiki/rdcport
|
|
||||||
+
|
|
||||||
+R8610: Found on the RDC evaluation board
|
|
||||||
+ http://www.ivankuten.com/system-on-chip-soc/rdc-r8610/
|
|
||||||
+
|
|
||||||
+AMRISC20000: Found in the MGB-100 wireless hard disk
|
|
||||||
+ http://tintuc.no-ip.com/linux/tipps/mgb100/
|
|
||||||
+
|
|
||||||
+S3282: Found in various NAS devices, including the Bifferboard
|
|
||||||
+ http://www.bifferos.com
|
|
||||||
+
|
|
||||||
+
|
|
||||||
+Kernel Configuration
|
|
||||||
+====================
|
|
||||||
+
|
|
||||||
+Add support for this CPU with CONFIG_X86_RDC321X. Ensure that maths
|
|
||||||
+emulation is included (CONFIG_MATH_EMULATION selected) and avoid MCE
|
|
||||||
+(CONFIG_X86_MCE not selected).
|
|
||||||
+
|
|
||||||
+
|
|
||||||
+CPU detection
|
|
||||||
+=============
|
|
||||||
+
|
|
||||||
+None of these chips support the cpuid instruction, so as with some
|
|
||||||
+other x86 compatible SoCs, we must check the north bridge and look
|
|
||||||
+for specific 'signature' PCI device config.
|
|
||||||
+
|
|
||||||
+The current detection code has been tested only on the Bifferboard
|
|
||||||
+(S3282 CPU), please send bug reports or success stories with
|
|
||||||
+other devices to bifferos@yahoo.co.uk.
|
|
||||||
+
|
|
||||||
+
|
|
||||||
+Credits
|
|
||||||
+=======
|
|
||||||
+
|
|
||||||
+Many thanks to RDC for providing the customer codes to allow
|
|
||||||
+detection of all known variants, without which this detection code
|
|
||||||
+would have been very hard to ascertain.
