mfd: rz-mtu3: Link time dependenciesThe new set of drivers for RZ/G2L MTU3a tries to enable compile-testing theindividual client drivers even when the MFD portion is disabled but gets itwrong, causing a link failure when the core is in a loadable module but theother drivers are built-in:x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply':pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write'x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable'arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get':rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read'It seems better not to add the extra complexity here but instead just usea normal hard dependency, so remove the #else portion in the header alongwith the "|| COMPILE_TEST". This could also be fixed by having slightly moreelaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper,but in practice it's already possible to compile-test all these driversby enabling the mtd portion.Fixes: 254d3a727421c ("pwm: Add Renesas RZ/G2L MTU3a PWM driver")Fixes: 0be8907359df4 ("counter: Add Renesas RZ/G2L MTU3a counter driver")Fixes: 654c293e1687b ("mfd: Add Renesas RZ/G2L MTU3a core driver")Signed-off-by: Arnd Bergmann Acked-by: Thierry Reding Reviewed-by: Biju Das Link: https://lore.kernel.org/r/20230719090430.1925182-1-arnd@kernel.orgSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/counter/Kconfig

Sun, 16 Apr 2023 17:36:53 +0000

counter: i8254: Introduce the Intel 8254 interface library moduleExposes consumer library functions providing support for interfacescompatible with the venerable Intel 8254 Programmable Interval Timer(PIT).The Intel 8254 PIT first appeared in the early 1980s and was usedinitially in IBM PC compatibles. The popularity of the original Intel825x family of chips led to many subsequent variants and clones of theinterface in various chips and integrated circuits. Although stillpopular, interfaces compatible with the Intel 8254 PIT are nowdaystypically found embedded in larger VLSI processing chips and FPGAcomponents rather than as discrete ICs.A CONFIG_I8254 Kconfig option is introduced by this patch. Moduleswanting access to these i8254 library functions should select thisKconfig option, and import the I8254 symbol namespace.Link: https://lore.kernel.org/r/f6fe32c2db9525d816ab1a01f45abad56c081652.1681665189.git.william.gray@linaro.org/Signed-off-by: William Breathitt Gray List of files: /linux-6.15/drivers/counter/Kconfig

Mon, 17 Apr 2023 19:50:50 +0000

counter: 104-quad-8: Migrate to the regmap APIThe regmap API supports IO port accessors so we can take advantage ofregmap abstractions rather than handling access to the device registersdirectly in the driver. With regmap we get boundary checks, read-writepermissions, operation synchronization locks, and more for free. Mostimportant of all, rather than rolling our own we utilize implementationsthat are known to work and gain from any future improvements and fixesthat come.Suggested-by: Andy Shevchenko Link: https://lore.kernel.org/r/1f1f7920d2be94aedb6fdf49f429fe6137c8cb24.1681753140.git.william.gray@linaro.org/Signed-off-by: William Breathitt Gray List of files: /linux-6.15/drivers/counter/Kconfig

7aa2ba0d - counter: 104-quad-8: Add IRQ support for the ACCES 104-QUAD-8

Wed, 29 Sep 2021 03:16:06 +0000

counter: 104-quad-8: Add IRQ support for the ACCES 104-QUAD-8The LSI/CSI LS7266R1 chip provides programmable output via the FLG pins.When interrupts are enabled on the ACCES 104-QUAD-8, they occur wheneverFLG1 is active. Four functions are available for the FLG1 signal: Carry,Compare, Carry-Borrow, and Index. Carry: Interrupt generated on active low Carry signal. Carry signal toggles every time the respective channel's counter overflows. Compare: Interrupt generated on active low Compare signal. Compare signal toggles every time respective channel's preset register is equal to the respective channel's counter. Carry-Borrow: Interrupt generated on active low Carry signal and active low Borrow signal. Carry signal toggles every time the respective channel's counter overflows. Borrow signal toggles every time the respective channel's counter underflows. Index: Interrupt generated on active high Index signal.These four functions correspond respectivefly to the following fourCounter event types: COUNTER_EVENT_OVERFLOW, COUNTER_EVENT_THRESHOLD,COUNTER_EVENT_OVERFLOW_UNDERFLOW, and COUNTER_EVENT_INDEX. Interruptspush Counter events to event channel X, where 'X' is the respectivechannel whose FLG1 activated.This patch adds IRQ support for the ACCES 104-QUAD-8.
