2008-01-28[POWERPC] QE: get rid of most device_types and modelAnton Vorontsov1-1/+4
Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data" and "fsl,qe-ic". Unfortunately it's still impossible to remove device_type = "qe" from the existing device trees because older u-boots are looking for it.

2008-01-23[POWERPC] fsl_soc: Fix get_immrbase() to use ranges, rather than reg.Scott Wood1-2/+10

2007-10-08[POWERPC] 85xx/86xx: refactor RSTCR reset codeKumar Gala1-0/+38
On the majority of 85xx & 86xx we have a register that's ability to assert HRESET_REQ to reset the board. We refactored that code so it can be shared between both platforms into fsl_soc.c and removed all the duplication in each platform directory. Signed-off-by: Kumar Gala <[email protected]>

MPC8568E-MDS have DS1374 chip on the I2C bus, thus let's use it. This patch also adds #address-cells and #size-cells to the I2C controllers nodes. p.s. DS1374 rtc class driver is in the -mm tree, its name is rtc-rtc-class-driver-for-the-ds1374.patch. Signed-off-by: Anton Vorontsov <[email protected]> Signed-off-by: Kumar Gala <[email protected]>

2007-10-03[POWERPC] Introduce new CPM device bindings.Scott Wood1-0/+2
This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

2007-10-03[POWERPC] CPM: Change from fsl,brg-frequency to brg/clock-frequencyScott Wood1-10/+14
As suggested by David Gibson, now that we have a separate node for the baud rate generators, it's better to use the standard clock-frequency property than a cpm-node-level fsl,brg-frequency property.

2007-09-14[POWERPC] fsl_soc.c cleanupScott Wood1-10/+17
1. Update the way get_brgfreq() finds things in the device tree. It now uses names that are less namespace polluting. The old names are supported until all boards are converted. 2. "size" is changed from unsigned int to int, to match what of_get_property() expects. Signed-off-by: Scott Wood <[email protected]> Signed-off-by: Kumar Gala <[email protected]>

Scan the device tree for i2c devices, check their "compatible" property against a hard-coded table, and, if found, register with i2c boardinfo. This provides the infrastructure needed to find i2c devices in the device tree and register them with the i2c subsystem.

2007-07-18Fix RGMII-ID handling in gianfarAndy Fleming1-0/+9
The TSEC/eTSEC can detect the interface to the PHY automatically, but it isn't able to detect whether the RGMII connection needs internal delay. So we need to detect that change in the device tree, propagate it to the platform data, and then check it if we're in RGMII. This fixes a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay for RGMII. Signed-off-by: Andy Fleming <[email protected]>
2007-07-10[POWERPC] 8xx: mpc885ads pcmcia supportVitaly Bordug1-0/+13
Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as of_device, so only arch/powerpc stuff is capable to use it, which now implies only mpc885ads reference board. To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.

Add function of_get_mac_address(), which obtains the best MAC address to use from the device tree by checking various properties in order. The order is: 'mac-address', then 'local-mac-address', then 'address'. It skips properties that contain invalid MAC addresses, which were probably not initialized by U-Boot.

2006-09-21POWERPC: Bring the fs_no calculation to the relevant SoC enumerationVitaly Bordug1-1/+7
The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

2006-09-21POWERPC: overhaul with cpm2_map mechanismVitaly Bordug1-0/+7
Incorporating the new way of cpm2 immr access, introduced in the previous patch, into CPM2 peripheral devices (fs_enet and cpm_uart). Both ppc and powerpc approved working( real actions taken in powerpc only, ppc just has a wrapper to keep init stuff consistent). Signed-off-by: Vitaly Bordug <[email protected]>
2006-09-21POWERPC: Get rid of remapping the whole immrVitaly Bordug1-1/+1
The stuff below cleans up the code attempting to remap the whole cpm2_immr early, as well as places happily assuming that fact. This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(<reg>), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense. Signed-off-by: Vitaly Bordug <[email protected]>
2006-09-21POWERPC: Add cpm2 stuff support to the fsl_soc.cVitaly Bordug1-5/+263
This patch contains necessary modifications to support the CPM2 SoC peripherals. For the time being, those are fs_enet Ethernet driver and cpm_uart serial. Written initially to support mpc8560, it also suites to the part of the large PQ2 (more specifically, mpc8260) family. Signed-off-by: Vitaly Bordug <[email protected]>
