* Improve imx31 interrupt code for PMIC and GPIOMichael Sevakis2017-01-29
| | | | | | | | | | Fix stuff that was bugging me about the way I did it at first. While messing around I found RDS code wasn't masking its GPIO ISR as it should, which might lead to two different interrupts messing with the static data. Change-Id: I54626809ea3039a842af0cc9e3e42853326c4193
* i.MX31: Fix a couple oopses from r31528Michael Sevakis2012-01-03
| | | | | | | | | | Enabled a PMIC event where it should be disabled. Used constant from wrong enum to get sense bits (??) which messed up main charger detection. Also remove an obsolete struct declaration. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31536 a1c6a512-1295-4272-9138-f99709370657
* i.MX31 - Dethreading operations continueMichael Sevakis2012-01-02
| | | | | | | | Dispense with "pmic" thread and process PMIC events directly within ISR. Add sense bit reading as part of the handling. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31528 a1c6a512-1295-4272-9138-f99709370657
* Gigabeat S: PMIC SPI improvement and bugfixes.Michael Sevakis2011-12-18
| | | | | | | | | | | | | | | | Nick some aspects from the as3525 ascodec driver to improve throughput in the beast's SPI communications by switching tranfer descriptors to the caller's stack and getting rid of thread synchronization. Fix a bug that suddenly became obvious that could permanently stall the SPI driver because all data could be shifted out before the interrupt could get serviced. In that case, it needs a kick to restart it. Should probably put the SPI interrupt priority above DVFS. A tweak to the event registration interface to simplify it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31353 a1c6a512-1295-4272-9138-f99709370657
* i.MX31/Gigabeat S: Actually enable DPTC which can set optimal voltage for ↵Michael Sevakis2010-05-04
| | | | | | 528MHz. Requires an SPI and PMIC interface rework because of the low-latency needs for the DPTC to work best with minimal panicing. SPI can work with multitasking and asynchronously from interrupt handlers or normal code. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25800 a1c6a512-1295-4272-9138-f99709370657

| | | | | | avoid overdrive voltage, just lower core voltage to 1.35V since voltage scaling shouldn't be required for frequencies lower than 399 MHz (according to Freescale BSP, which set all working points to 1.35V for those frequencies). Perhaps battery life will improve as well (cross fingers :). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25506 a1c6a512-1295-4272-9138-f99709370657

* Gigabeat S:Michael Sevakis2008-05-21
| | | | | | | | | | | | | 1) Rework event handling and static registration mechanism. No target- specific code in mc13783 driver. GPIO event driver interfaces more cleanly. 2) Somewhat related - enable thread priority for bootloader which is desireable here (ffs is used for GPIO event enabling anyway and that goes along with priority). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17593 a1c6a512-1295-4272-9138-f99709370657
