ASoC updates in 3.6

Linux v3.6 was another quiet release for ASoC with just a single notable framework feature being merged:

• Added the ability to add and remove DAPM paths dynamically, mostly for reparenting on clock changes.
• New machine drivers for Marvell Brownstone, ST-Ericsson Ux500 and ttc-dkp.
• New CPU drivers for Blackfin BF6xx SPORTs in I2S mode, Marvell MMP, Synopsis Designware I2S controllers, SPEAr DMA, S/PDIF
• New CODEC drivers for Dialog DA732x, ST STA529, ST-Ericsson AB8500, TI Isabelle Wolfson Microelectronics WM5102

UK landline non-security (and Orange clue)

Yesterday when I got in from work I got my second letter in as many months through from BT saying that my account was being closed as my landline was being transferred to another provider. This was the first I’d heard of this and it causes a cancellation charge so I called to complain; the first time I did this they said they couldn’t tell me anything about who the line had been transferred to. They did tell me that there was no equivalent of PAC or MAC for landlines and that the only thing stopping this happening is the two week delay in implementing.

This time BT felt able to tell me that the line had been transferred to Orange so I phoned Orange. Orange told me that the phone number had indeed been transferred to them in the name of someone else. They also said that they had no intention of attempting to carry out any authentication that lines being transferred to them are owned by the person they’re being transferred to – I explicitly asked them if anyone could just do this for any phone number and they confirmed that this is indeed the case.

BT claim they can’t block transfers for regulatory reasons; Orange claim this is possible and that I should just do that. I’ve asked Orange to put a note on the account (which was the best they claimed they could do) and complained to OFCOM (who won’t really talk to me without a formal escalation from the phone providers) but none of this really helps given the gaping security holes in the system. You really should need more information than just the phone number itself to transfer a number.

On the slightly bright side I still appear to have phone service; presumably currently paid for by whoever is initiating the transfers.

regulator updates in 3.6

Linux 3.6, which was released earlier today, saw continuing improvements in the factoring out of common code in the API – lots of new features making drivers smaller and easier to write!

• Initial framework support for GPIO controlled enable signals, saving a bunch of code in drivers.
• Move fixed regulator enable time and voltage mapping table specifications to data.
• Used some of the recent framework enhancements to make voltage change notifications more useful, passing the voltage in as an argument to the notification.
• New drivers for Maxim MAX77686, TI LP872x and LP8788, Samsung S2MPS11, Wolfson Arizona microphone supplies and LDOs

regmap updates in 3.6

Linux 3.6 was a very quiet release for regmap:

• Support for buses and devices specifying their endianness, providing some performance improvements for MMIO devices.
• Support for wake IRQs in regmap-irq.

Speaking at ELC-E: “regmap: The Power of Subsystems and Abstractions”

I will be speaking at ELC-E in Barcelona this year, with a talk entitled regmap: The Power of Subsystems and Abstractions. I look forward to seeing some of you at the conference, perhaps even in the audience!
