* OMAP: UART: drop OMAP_TAG_UART, enable all UARTs, auto-disabled on idleKalle Valo2009-08-281-5/+0
| | | | | | | | | | | | | | | | OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

* OMAP3 SDRC: add support for 2 SDRAM chip selectsJean Pihet2009-07-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | Some OMAP3 boards (Beagle Cx, Overo, RX51, Pandora) have 2 SDRAM parts connected to the SDRC. This patch adds the following: - add a new argument of type omap_sdrc_params struct* to omap2_init_common_hw and omap2_sdrc_init for the 2nd CS params - adapted the OMAP boards files to the new prototype of omap2_init_common_hw - add the SDRC 2nd CS registers offsets defines - adapt the sram sleep code to configure the SDRC for the 2nd CS Note: If the 2nd param to omap2_init_common_hw is NULL, then the parameters are not programmed into the SDRC CS1 registers Tested on 3430 SDP and Beagleboard rev C2 and B5, with suspend/resume and frequency changes (cpufreq).

* ARM: OMAP2/3: Add generic smc91x support when connected to GPMCTony Lindgren2009-05-281-81/+22
| | | | | | | | | | | | | Convert the board-rx51 smc91x code to be generic and make the boards to use it. This allows future recalculation of the timings when the source clock gets scaled. Also correct the rx51 interrupt to be IORESOURCE_IRQ_HIGHLEVEL. Thanks to Paul Walmsley <paul@pwsan.com> for better GPMC timing calculations. Signed-off-by: Tony Lindgren <tony@atomide.com>

* | [ARM] OMAP2 SDRC: add SDRAM timing parameter infrastructurePaul Walmsley2009-02-081-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | For a given SDRAM clock rate, SDRAM chips require memory controllers to use a specific set of timing minimums and maximums to transfer data reliably. These parameters can be different for different memory chips and can also potentially vary by board. This patch adds the infrastructure for board-*.c files to pass this timing data to the SDRAM controller init function. The timing data is specified in an 'omap_sdrc_params' structure, in terms of SDRC controller register values. An array of these structs, one per SDRC target clock rate, is passed by the board-*.c file to omap2_init_common_hw(). This patch does not define the values for different memory chips, nor does it use the values for anything; those will come in subsequent patches. linux-omap source commit is bc84ecfc795c2d1c5cda8da4127cf972f488a696.

* ARM: OMAP2: Change 24xx to use new register accessPaul Walmsley2008-04-141-9/+14
| | | | | | | | | | | | | | | | | | | This patch changes 24xx to use new register access, except for clock framework. Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses. Also note that sleep.S removes some unused registers addresses. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* [NET] smc91x: Make smc91x use IRQ resource trigger flagsRussell King2008-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | smc91x is shared between many different platforms. Each platform needs to specify the interrupt type, and in some cases the irq type depends on more than just the build configuration - it depends on runtime checks. Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide a way for these flags to be passed via the IRQ resource itself. Note that IRQF_TRIGGER_* constants are intentionally defined to correspond with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that the low bits of PCI iomem resources correspond with the BAR flag bits. Also provide a way to configure smc91x to read the IRQ flags from the resource. Once all platforms have been converted over (signified by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should be removed.
