soc: ti: fix irq-ti-sci link error

2019-07-01T22:26:09+00:00

The irqchip driver depends on the SoC specific driver, but we want to be able to compile-test it elsewhere: WARNING: unmet direct dependencies detected for TI_SCI_INTA_MSI_DOMAIN Depends on [n]: SOC_TI [=n] Selected by [y]: - TI_SCI_INTA_IRQCHIP [=y] && TI_SCI_PROTOCOL [=y] drivers/irqchip/irq-ti-sci-inta.o: In function `ti_sci_inta_irq_domain_probe': irq-ti-sci-inta.c:(.text+0x204): undefined reference to `ti_sci_inta_msi_create_irq_domain' Rearrange the Kconfig and Makefile so we build the soc driver whenever its users are there, regardless of the SOC_TI option.

soc: ti: Add MSI domain bus support for Interrupt Aggregator

2019-05-01T09:49:17+00:00

With the system coprocessor managing the range allocation of the inputs to Interrupt Aggregator, it is difficult to represent the device IRQs from DT. The suggestion is to use MSI in such cases where devices wants to allocate and group interrupts dynamically. Create a MSI domain bus layer that allocates and frees MSIs for a device. APIs that are implemented: - ti_sci_inta_msi_create_irq_domain() that creates a MSI domain - ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the specified device and resource. - ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device. - ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

soc: ti: pm33xx: AM437X: Add rtc_only with ddr in self-refresh support

2019-04-08T17:39:01+00:00

During RTC-only suspend, power is lost to the wkup domain, so we need to save and restore the state of that domain. We also need to store some information within the RTC registers so that u-boot can do the right thing at powerup. The state is entered by getting the RTC to bring the pmic_power_en line low which will instruct the PMIC to disable the appropriate power rails after putting DDR into self-refresh mode. To bring pmic_power_en low, we need to get an ALARM2 event. Since we are running from SRAM at that point, it means calculating what the next second is (via ASM) and programming that into the RTC. This patch also adds support for wake up source detection. Signed-off-by: Keerthy Signed-off-by: Dave Gerlach Signed-off-by: Tony Lindgren

soc: ti: knav_dma: Use proper enum in pktdma_init_chan

Clang warns when one enumerated type is implicitly converted to another: drivers/soc/ti/knav_dma.c:601:20: warning: implicit conversion from enumeration type 'enum dma_data_direction' to different enumeration type 'enum dma_transfer_direction' [-Wenum-conversion] chan->direction = DMA_NONE; ~ ^~~~~~~~ 1 warning generated. While DMA_NONE and DMA_TRANS_NONE have different values, there is no functional change because direction is never checked against DMA_NONE, only against DMA_MEM_TO_DEV and DMA_DEV_TO_MEM.

soc: ti: QMSS: Fix usage of irq_set_affinity_hint

2018-11-02T18:22:09+00:00

The Keystone QMSS driver is pretty damaged, in the sense that it does things like this: irq_set_affinity_hint(irq, to_cpumask(&cpu_map)); where cpu_map is a local variable. As we leave the function, this will point to nowhere-land, and things will end-up badly. Instead, let's use a proper cpumask that gets allocated, giving the driver a chance to actually work with things like irqbalance as well as have a hypothetical 64bit future.
