2008-12-02[ARM] pxa/MioA701: improve power supply sourcesRobert Jarzmik
Take advantage of the newly created wm97xx battery driver and remove useless code in mioa701 board code. Add also the ac connection detect capability after the matching gpio was discovered. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa/MioA701: discovered new gpio definitions.Robert Jarzmik
The charger enable gpio is straight (1 means draw from USB Vbus, 0 mean do not draw). The USB Vbus sensing is inverted (1 means no Vbus voltage sensed, 0 means Vbus voltage present). Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa/MioA701: change reset function to preserve RTC.Robert Jarzmik
Change the halt and reboot method from gpio based to "jump to ROM IPL beginning". This gives control back to IPL, which without PowerOn key pressed, will put the device into deep sleep until PowerOn is pressed for 1 second. But this has the benefit of keeping the RTC registers across reboots, which is good for OS change.

2008-12-02[ARM] pxa/MioA701: add camera support for Mio A701 board.Robert Jarzmik

2008-12-02[ARM] pxa/MioA701: remove KConfig leds driver requirementRobert Jarzmik
Since mioa701 board has migrated to the mfp architecture, low power gpio setup is now correctly handled even when gpio led driver is not loaded, and leds and vibrator don't stay activated in suspend mode (especially vibrator). Remove the not needed anymore dependency. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2008-12-02[ARM] pxa: cpufreq-pxa2xx: sdram_rows detection supportPhilipp Zabel
This patch implements Eric Miao's idea to detect the correct value of sdram_rows by inspecting the MDCNFG register settings. It is only tested on two pxa27x devices with 64MB RAM (magician and hx4700) so far. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa: cpufreq-pxa2xx: allow frequency table selectionMarc Zyngier
Following the removal of the "->policy" usage for PXA255 in patch 459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove policy->governor setting in drivers initialization), this patch introduces an option (called "pxa255_turbo_table") to select either the "run" or "turbo" frequency table. It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing. Tested on an Arcom/Eurotech Viper. Signed-off-by: Marc Zyngier <maz@misterjones.org> Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2008-12-02[ARM] pxa: move AC97 register definitions into dedicated regs-ac97.hEric Miao

2008-12-02[ARM] pxa: add support for additional GPIOs on PXA26xEric Miao
Original patch from Marek Vasut, the problems with PXA26x are: 1. there are additional 4 GPIOs 86,87,88,89 have their direction bits inverted in GPDR2, as well as their alternate function bits being '1' for their GPIO functionality in GAFRx 2. there is no easy way to decide if the processor is a pxa26x or a pxa250/pxa255 at run-time, so the assumption here is the pxa26x will be treated as one of the pxa25x variants, and board code should have a better knowledge of the processor it is featured Introduce pxa26x_init_irq() for the second purpose, and treat the additional GPIOs > 85 on PXA25x specially. Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code a bit when PXA26x support isn't needed. Board config options have to select this to enable the support for PXA26x. __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x isn't selected.

2008-12-02Revert "[ARM] pxa: introduce cpu_is_pxa26x()"Eric Miao
This reverts commit da1a3dc0ebb4f9209a1939eaa6b18901e0cd7bc0. The originally proposed way in the above commit is incorrect. And there is no easy way to distinguish between pxa25x and pxa26x at run-time. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa: use 'pxa_last_gpio' instead of 'gpio_nr' in mfp-pxa2xx.cEric Miao
The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we already have that variable, remove the unnecessary 'gpio_nr' now. Also, fix the incorrect GPIO number passed in pxa27x_init_irq(). Note: pxa_last_gpio should be initialized earlier, and this is true since it's been assigned in machine_desc->init_irq().

2008-12-02[ARM] pxa: add muxed gpio wakeup sources on pxa2xx architecturesRobert Jarzmik

2008-11-09[ARM] iop: iop3xx needs registers mapped uncached+unbufferedRussell King
Mikael Pettersson reported: The 2.6.28-rc kernels fail to detect PCI device 0000:00:01.0 (the first ethernet port) on my Thecus n2100 XScale box. There is however still a strange "ghost" device that gets partially detected in 2.6.28-rc2 vanilla. The IOP321 manual says: The user designates the memory region containing the OCCDR as non-cacheable and non-bufferable from the IntelR XScaleTM core. This guarantees that all load/stores to the OCCDR are only of DWORD quantities. Ensure that the OCCDR is so mapped. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
