* arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre2010-10-201-2/+0
| | | | | | | | | | | | | | | Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>
* [ARM] orion5x: Base support for DNS-323 rev C1Benjamin Herrenschmidt2010-07-161-62/+305
| | | | | | | | | | This patch adds the base support for this new HW revision to the existing dns323-setup.c file. The SoC seems to be the same as rev B1, the GPIOs are all wired differently though and the fan control isn't i2c based anymore.

* [ARM] orion5x: Set links to solid on D-Link DNS-323Martin Michlmayr2010-07-161-2/+1
| | | | | | | | | | | | | | | Among other changes, commit b2a731aa ("D-link DNS-323 revision A1 power LED") changed the default behaviour of the power LED from solid to blinking. This was done to match the original DNS-323 firmware which blinks during the boot process and sets the LED to solid when booting has completed. However, the downside of this behaviour is that it requires userland code to change the LED, even for those who don't care about the behaviour of the original firmware. Therefore, change it to solid again and let those who care about the original behaviour change the behaviour from userland.

* leds: leds-gpio: Change blink_set callback to be able to turn off blinkingBenjamin Herrenschmidt2010-05-261-10/+12
| | | | | | | | | | | | | | | | | | | The leds-gpio blink_set() callback follows the same prototype as the main leds subsystem blink_set() one. The problem is that to stop blink, normally, a leds driver does it in the brightness_set() callback when asked to set a new fixed value. However, with leds-gpio, the platform has no hook to do so, as this later callback results in a standard GPIO manipulation. This changes the leds-gpio specific callback to take a new argument that indicates whether the LED should be blinking or not and in what state it should be set if not. We also update the dns323 platform which seems to be the only user of this so far.

* [ARM] dns323-setup.c: fix WARN() when bootingArnaud Patard2010-05-031-0/+1
| | | | | | | | | | | | | Since commit b2a731aa5cbca7e0252da75e16de7ae5feb1313a, dns323_init() is setting the power led gpio direction with gpio_direction_output() but doesn't request the gpio before (which is not permitted by the gpio layer afaik). This behaviour is triggering a WARN() at boot time.

* [ARM] orion5x: D-link DNS-323 revision A1 power LEDLaurie Bradshaw2010-02-101-3/+33
| | | | | | | | | | | | | | | | | This patch fixes the power LED on DNS-323 revision A1, and adds timer support for (hopefully) both A1 and B1 revisions. Power LED on revision A1 is active low and also requires GPIO 4 to be low to work. Tested on my DNS-323 revision A1. I have set the default trigger to timer as that replicates the behaviour of the original firmware, userspace can change the trigger at the end of the boot process providing a useful indication that booting has completed.

* [ARM] orion5x: D-link DNS-323 rev. B1 power-offErik Benada2010-01-241-6/+27
| | | | | | | | | | | | This patch fixes power LED blinking and power-off on DNS-323 rev. B1. GPIO pin 3 has to be set to 1 to stop power LED blinking and to allow the LED to be controlled via leds-gpio. This pin has to be also set to 1 for power-off to work. To power-off the rev. B1 machine, pin 8 has to be set to 1 and then set to 0 to do actual power-off. Tested on my DNS-323 rev.

| | | | | | | | | | The 88F5182 found in the DNS-323 rev B1 (and some other devices, such as the CH3SNAS) require different initialisation of the SATA controller and MPP registers. Tested on a DNS-323 rev B1. Signed-off-by: Matt Palmer <mpalmer@hezmatt.org>

* mv643xx_eth: remove force_phy_addr fieldLennert Buytenhek2008-09-051-1/+1
| | | | | | | | | | | | | | | Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address'). If we are a bit smarter about the encoding of the phy_addr field, we can avoid the need for a second field -- this patch does that. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

* [ARM] Orion: avoid setting ->force_phy_addrLennert Buytenhek2008-06-221-1/+0
| | | | | | | | | | | | | | | | The mv643xx_eth platform data field ->force_phy_addr only needs to be set if the passed-in ->phy_addr field is zero (to distinguish the case of not having specified a phy address (force_phy_addr = 0) from the case where a phy address of zero needs to be used (force_phy_addr = 1.)) Also, the ->force_phy_addr field will hopefully disappear in a future mv643xx_eth reorganisation. Therefore, this patch deletes the ->force_phy_addr field initialiser from all Orion board code.

* [ARM] Orion: remove error printks in ->map_irq() implementationsLennert Buytenhek2008-06-221-2/+0
| | | | | | | | | | | | | | | If all PCI devices are working as expected, the error printks in the various implementations of ->map_irq() doesn't really provide any useful info. And if something is not working as expected, turning on pci=debug gives you more useful information than the printk calls in ->map_irq(), since the former also tells you which devices _did_ get IRQs successfully assigned. Therefore, delete these printks entirely. Spotted by Russell King. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Russell King <linux@arm.linux.org.uk>

* [ARM] Orion: move EHCI/I2C/UART peripheral init into board codeLennert Buytenhek2008-06-221-20/+20
| | | | | | | | | | | | | | | | | This patch moves initialisation of EHCI/I2C/UART platform devices from the common orion5x_init() into the board support code. The rationale behind this is that only the board support code knows whether certain peripherals have been brought out on the board, and not initialising peripherals that haven't been brought out is desirable for example: - to reduce user confusion (e.g. seeing both 'eth0' and 'eth1' appear while there is only one ethernet port on the board); and - to allow for future power savings (peripherals that have not been brought out can be clock gated off entirely).

* [ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisationLennert Buytenhek2008-05-171-1/+1
| | | | | | | | | | | | | | | | | | | | Whereas most Orion 5x machine support code would initialise the PCI subsystem with nr_controllers in their struct hw_pci set to 2, the DNS323 and Kurobox Pro machine support code had nr_controllers set to 1. This was presumably done because on those two machines, the PCI(-X) controller (nr == 1) isn't used, requiring initialisation of only the PCIe controller (nr == 0.) However, not initialising the PCI(-X) controller on boards that don't use it leads to a situation where both the PCIe and the PCI(-X) controller think that their root bus is zero, and it messes up IRQ assignment. This patch changes the DNS323 and Kurobox Pro support code to always use nr_controllers == 2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current orion5x board ->map_irq() routines check whether a given bus number lives on the PCIe controller by comparing it with the PCIe controller's primary bus number. This doesn't work in case there are multiple buses in the PCIe domain, i.e. if there exists a PCIe bridge on the primary PCIe bus. This patch adds a helper function (orion5x_pci_map_irq()) that returns the IRQ number for the given PCI device if that device has a hard-wired IRQ, or -1 otherwise, and makes each board's ->map_irq() function use this helper function.

Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme.
