* ARM: davinci: remove intc related fields from davinci_soc_infoBartosz Golaszewski2019-02-191-98/+0Star

* ARM: davinci: cp-intc: use the new-style config structureBartosz Golaszewski2019-02-191-1/+1
| | | | | | | | | | | | | | | | | | Modify the cp-intc driver to take all its configuration from the new config structure. Stop referencing davinci_soc_info in any way. Move the declaration for davinci_cp_intc_init() to irq-davinci-cp-intc.h and make it take the new config structure as parameter. Convert all users to the new version. Also: since the two da8xx SoCs default all irq priorities to 7, just drop the priority configuration at all and hardcode the channels to 7. It will simplify the driver code and make our lives easier when it comes to device-tree support.

* ARM: davinci: cp-intc: add a wrapper around cp_intc_init()Bartosz Golaszewski2019-02-191-0/+5
| | | | | | | | | | | | | We're going to extend the cp_intc_init() function with a config structure so we can drop the intc-related fields from davinci_soc_info. Once we do it, we won't be able to use this routine directly as the init_irq callback. Wrap the calls in additional helpers that don't take parameters and can be assigned to init_irq.

* ARM: davinci: make irqs.h a local headerBartosz Golaszewski2019-02-191-1/+1
| | | | | | | | | | | | | | The existence of irqs.h in mach-davinci/include/mach only makes sense without SPARSE_IRQ as it's then expected to define NR_IRQS and is included from asm/irq.h. As we now support SPARSE_IRQ, this header can be moved to mach-davinci and used as the source of HW interrupt numbers. While updating the includes in various files - also rearrange the headers by directory (linux/asm/mach).

| | | | | | | | | | | | Once we select SPARSE_IRQ, the interrupt numbers defined in mach/irqs.h will only signify the hardware interrupt offsets, not the interrupt numbers seen by linux. Introduce a wrapper macro that translates the hwirq number to virtual numbers. For now it's just a dummy. Use that macro when specifying the interrupts in resources for platform devices.

| | | | | | | | | | | | | | | Commit 587f7a694f01 ("gpio: davinci: Use dev name for label and automatic base selection") broke the GPIO support on DaVinci boards in legacy mode by allowing gpiolib to set the GPIO base automatically. DaVinci board files use the legacy GPIO API with hard-coded GPIO line numbers. Use the new fields in struct davinci_gpio_platform_data to manually set the GPIO base to 0.

| | | | | | | | | | | | | | | | | | | | This moves the call of davinci_clk_init() from map_io to init_time for all boards. This is the proper place to init clocks. This is also done in preparation for moving to the common clock framework. dm646x is a special case because we need to handle different ref_clk rates depending on which board is being used. The clock init in this case is modified to set the rate before registering the clocks instead of using davinci_set_refclk_rate() to recalculate the entire clock tree after all of the clocks are registered. Also, the cpu_clks field is removed from struct davinci_soc_info since it is no longer needed. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

With this patch, the ioremap() interception code can properly translate addresses only after davinci_soc_info has been initialized. Consequently, in soc-specific init functions, davinci_common_init() has to happen before any ioremap() attempts. The da8xx init sequence has been suitably modified to meet this restriction.

| * Davinci: timer - use ioremap()Cyril Chemparathy2010-05-131-2/+2
| | | | | | | | | | | | | | | | This patch eliminates IO_ADDRESS() usage for Davinci timer definitions. The timer code has correspondingly been modified to ioremap() MMRs instead. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
| * Davinci: jtag_id - use ioremap()Cyril Chemparathy2010-05-131-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | This patch replaces the jtag id base info in davinci_soc_info with a physical address which is then ioremap()ed within common code. This patch (in combination with a similar change for PSC) will allow us to eliminate the SYSCFG nastiness in DA8xx code.

| * Davinci: gpio - use ioremap()Cyril Chemparathy2010-05-131-1/+1
| | | | | | | | | | | | | | | | | | This patch modifies the gpio_base definition in davinci_soc_info to be a physical address, which is then ioremap()ed by the gpio initialization function. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
| * Davinci: watchdog reset separation across socsCyril Chemparathy2010-05-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.

| * Davinci: gpio - controller type supportCyril Chemparathy2010-05-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows for gpio controllers that deviate from those found on traditional davinci socs. davinci_soc_info has an added field to indicate the soc-specific gpio controller type. The gpio initialization code then bails out if necessary. More elements (tnetv107x) to be added later into enum davinci_gpio_type.

* | DA830: fix USB 2.0 clock entrySergei Shtylyov2010-05-141-1/+1
|/ | | | | | | | | | | DA8xx OHCI driver fails to load due to failing clk_get() call for the USB 2.0 clock. Arrange matching USB 2.0 clock by the clock name instead of the device. (Adding another CLK() entry for "ohci.0" device won't do -- in the future I'll also have to enable USB 2.0 clock to configure CPPI 4.1 module, in which case I won't have any device at all.)

* davinci: clkdev cleanup: remove clk_lookup wrapper, use clkdev_add_table()Kevin Hilman2010-02-041-1/+1
| | | | | | | Remove unneeded 'struct davinci_clk' wrapper around 'struct clk_lookup' and use clkdev_add_table() to add the list of clocks in one go. Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* davinci: da8xx/omapl1: add support for the second sysconfig moduleSekhar Nori2010-02-041-4/+4
| | | | | | | | | | | | | OMAP-L138 adds a second SYSCFG region having useful functionality like deep sleep, pull up/down control and SATA clock stop. This patch makes provision for accessing registers from second SYSCFG region in da8xx code. Note that OMAP-L137 has a single SYSCFG region.
