| | * | [ARM] 5308/1: Fix Viper ISA IRQ handlingMarc Zyngier2008-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ISA IRQ renumbering broke the Viper ISA code in interesting ways. It originally assumed that ISA interrupt were numbered in the order that is defined by the CPLD registers. Unfortunately, this is no longer the case. Furthermore, the viper_irq_handler() function being a chained IRQ handler, it must ACK the interrupt by itself, or the handler will be immediately reentered, with the expected damages. This fix was made possible thanks to the help of David Raeman, who provided debug information and tested each version of this patch.

This will allow compiling sleep code for both chips into the same kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the omap24xx_cpu_suspend instead of loading the values since the only. Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL instead of the address as that's what omap24xx_cpu_suspend expects to determine between DDR and SDR. This bug has not been noticed as the boards seem to have DDR instead of SDR. Note that some PM patches are still missing.

This doesn't lend itself to static checking, nor to easy understanding of the code. And so, OMAP_MPUIO_BASE gets to be the right type - integer like since it's a physical address, not a MMIO pointer.

Currently, this feature only applies to USBHOST and USBTLL module context when the USBHOST or CORE powerdomains enter a low-power sleep state[1]. This feature avoids re-enumeration of USB devices when the powerdomains return from idle, which is potentially time-consuming. This patch adds support for enabling and disabling hardware save-and-restore to the powerdomain code. Three new functions are added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and pwrdm_can_hdwr_sar(). A new struct powerdomain "flags" field is added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with SAR support. Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com> for clarifying the purpose of these bits. 1. For the USBHOST controller module, context loss occurs when the USBHOST powerdomain enters off-idle. For USBTLL, context loss occurs either if CORE enters off-idle, or if the CORE logic is configured to turn off when CORE enters retention-idle (OSWR). 34xx ES2 TRM 4.8.6.1.1, 4.8.6.1.2 Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
