All in - Galaxy S6 & S6 edge on AT&T carry Samsung "Shannon" LTE modems, Wolfson DACs
UPDATE (April 7 2015):Clarified that only the Galaxy S6 & S6 edge on AT&T have Samsung-made baseband chips.

Patent and technology research firm Chipworks published a report detailing the hardware components used in the Samsung Galaxy S6 & S6 edge. Of note is that Samsung's latest smartphones feature in-house made components in abundance. The chipset (Exynos 7420), the RAM memory ( K3RG3G30MM-DGCH 3GB LPDDR4 SDRAM) & flash memory (KLUBG4G1BD 32GB NAND Flash), and the image processor (C2N8B6) are all Samsung made, but most importantly, the modem and Wi-Fi module are built in-house as well. The S6 & S6 edge on AT&T carry the Samsung "Shannon" 333 modem and 3853B5 Wi-Fi Module, which sets a precedent for today's Android devices. 

The vast majority of 3G/4G-connected devices sold in Western markets from name manufacturers have been relying on Qualcomm chipsets and their integrated multiband LTE modems. The Galaxy S6 and S6 edge make no exception, as most of their versions around global carriers and markets employ Qualcomm basebands. However, Samsung is the first to eschew the application processor, graphics unit, and baseband provided by the US chipset powerhouse in favor of its own solutions, and put its product on sale with a large American carrier. This serves to illustrate the insatiable growth ambitions of Samsung's semiconductor division, which is seeking success beyond supplying flash memory for global clients and making chipsets for the Apple iPhone. The market is due for a shakeup in the next couple of years if Samsung establishes itself as an all-in semiconductor supplier. Recent analyst expectations go as far as suggesting Qualcomm might be looking to adopt Samsung's industry-leading 14nm mobile AP manufacturing process for its own products.
