These changes: * Rework the pinctrl API as we discussed at Linaro Connect. * Allow specifying pin config settings in the mapping table in addition to mux options, as we agreed upon at Linaro Connect. * Various cleanups and refactorings aimed at supporting the changes above. TODO in this patch set: * Test build of non-Tegra platforms. * Test build with pinmux/pinconf disabled. ... but I figure it was a good idea to send out for comments ASAP. TODO in future patch sets: * Implement device tree support in pinctrl core and a pinctrl driver. * Remove pin config APIs from pinctrl now that the mapping table supports pin config? I've tested this all on a couple Tegra boards, including hacking in a single pin config and dummy state mapping table entry. I've got patches for Tegra boards that use the explicit pin config APIs, and need to convert them to using the pin config mapping table entries for more complete testing. (In the diffstat below, I /think/ the first 19 patches are a net negative in line-count, and only the last patch, which implements a new feature, adds a significant number of lines) Stephen Warren (20): pinctrl: pinctrl_register_mappings() shouldn't be __init pinctrl: use list_add_tail instead of list_add pinctrl: Store mapping table as a list of chunks pinctrl: Record a pin owner, not mux function, when requesting pins pinctrl: Re-order pinmux.[ch] to match each-other pinctrl: Re-order pinconf.[ch] to match each-other pinctrl: core.c/h cleanups pinctrl: Assume map table entries can't have a NULL name field pinctrl: Disallow map table entries with NULL dev_name field pinctrl: Assume map table entries can't have a NULL ctrl_dev_name field pinctrl: Downgrade pinctrl_get warning when no maps are found pinctrl: Use dev_*() instead of pr_*(), add some msgs, minor cleanups pinctrl: Error if mapping table's control dev can't be found pinctrl: Allocate sizeof(*p) instead of sizeof(struct foo) pinctrl: Fix and simplify locking pinctrl: Refactor struct pinctrl handling in core.c vs pinmux.c pinctrl: Add usecount to pins for muxing pinctrl: Fix pinconf_groups_show() to emit newline pinctrl: API changes to support multiple states per device pinctrl: Enhance mapping table to support pin config operations Documentation/pinctrl.txt | 244 +++++++---- arch/arm/mach-u300/core.c | 28 +- drivers/pinctrl/core.c | 936 +++++++++++++++++++++---------------- drivers/pinctrl/core.h | 100 +++-- drivers/pinctrl/pinconf.c | 288 ++++++++++-- drivers/pinctrl/pinconf.h | 45 ++- drivers/pinctrl/pinmux.c | 578 ++++++++--------------- drivers/pinctrl/pinmux.h | 61 ++-- drivers/tty/serial/sirfsoc_uart.c | 12 +- include/linux/pinctrl/consumer.h | 55 ++- include/linux/pinctrl/machine.h | 131 ++++-- include/linux/pinctrl/pinctrl.h | 1 - 12 files changed, 1438 insertions(+), 1041 deletions(-) -- 22.214.171.124 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to firstname.lastname@example.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
